All plants have basic needs.

Basic NeedsSunlight—Plants get energy from the Sun. Chlorophyll found in plant leaves uses sunlight to change water, minerals, and carbon dioxide into food. This process is called photosynthesis.

Water—Plants must have water because it helps carry nutrients from the soil to the plant's roots. Water is a part of plant cells and is a main ingredient for photosynthesis.

Minerals—Plants need soil because they use it to get water, nutrients, and minerals.

Air—Plants also get nutrients from the air. During photosynthesis, plants take in carbon dioxide from the air and release oxygen.

Space—Plants also need space to grow. If there are too many plants for the amount of sunlight, soil, minerals, or space, some of the plants will not survive

Plant PartsRoots—Roots anchor the plant in the soil, take in water from the soil, and take in nutrients from the soil.

Leaves—Leaves are where photosynthesis mainly takes place. Leaves take in carbon dioxide from the air and absorb sunlight energy. Both of these things are needed in order for the plant to make food through photosynthesis. Leaves exchange gases with the atmosphere through holes called stoma.

Stems—Stems provide structure for the plant and allow water and nutrients to travel throughout the plant. The stems of some plants can also help the plant to reproduce. If the stem is planted in the ground correctly, a new plant will grow

Both of these things are needed in order for the plant to make food through photosynthesis. Leaves exchange gases with the atmosphere through holes called stoma.

• Plant part that is responsible for food production through Photosynthesis.

• The Leaves/Needles are also where gas exchange takes place. Carbon Dioxide goes in, and Oxygen comes out.

Leaves /Needles

Parts of the Plant

Stems provide structure for the plant and allow water and nutrients to travel throughout the plant

• Plant part that is responsible for supporting the upper plant parts.

• The Stem also transports water/nutrients from the roots to the leaves and transports food (sugar) back from the leaves down to the roots.

Stem

Parts of the Plant

Flowers allow the plant to reproduce. They produce pollen and also the eggs that the pollen will fertilize. Once a flower is pollinated, the flowers can produce seeds and fruit. The petals are the parts of the flower that attract pollinators, such as insects. Petals are usually brightly colored.

• Plant part that is responsible for plants reproducing new seeds through plant reproduction.

FLOWERS/CONES

• Plant part that is formed around the seed of a flowering plant.

FRUITS

Parts of the Plant

Roots anchor the plant in the soil, take in water from the soil, and take in nutrients from the soil.

• Plant part that is responsible for giving the plant water and nutrients from the ground.

• Roots are also the anchor that holds the plant in the ground.

Roots

Parts of the PlantSeeds of a plant can grow into new plants once they get into the soil. This allows the plant to reproduce. Some seeds have special structures to help them get to a new piece of ground. Dandelion seeds have light hairs that catch the wind to blow them away. Burrs have sharp spines that get caught in animals' fur, carrying the seeds away.

• Plant part that is responsible for making a new plant (Embryo).

• Seeds have enough food in them to start an Embryo and are usually found in the plant’s fruit.

Reproduction in flowering plants

• Flowering plants can reproduce from seeds.

• To reproduce, plants produce flowers which develop into fruits and seeds.

• For fruits and seeds to be produced, the flowers must be pollinated and fertilized.

The Parts of a Flower• Sepals protect the bud until

it opens.• Petals attract insects.• Stamens make pollen.• Pistil contain the ovary

which contains the ovules (eggs).

• When fertilized, ovules grow into fruits which contain seeds.

Parts of a Flower

Parts of a flower

• The male part of the flower is the stamen which include the anther and filament. – The anther produces pollen grains.

• The female parts of the flower is the pistil which includes the stigma, style, ovary and ovule.

Flowering Plant Reproduction

• Pistil• Ovary• Egg• Stamen

• Pollen• Sperm• Pollination• Fertilization

The Stamen:Male Reproductive Part of a Flower

Anther: Pollen grains (sperm cells) grow in the anther.

StigmaStyleOvary (carpel)Eggs(ovules)

Pollination

• Pollination is the transfer of pollen grains from the anther to the stigma of a flower.– The pollen grains can be transferred within the

same flower.

stigma pollen grains from anther

Pollination= moving

from the stamen to the pistil

Pollination

• Pollen grains can be transferred by wind, insects, bats and birds.

– The pollen grains can also be transferred from one flower to another.

What is Pollination? Gizmos: Flower Pollination

Pollination is the act of transferring pollen grains from the male anther of the stamen to the female stigma.

Pollen lands on a female pistil, sperm cells move down to the ovary, fertilizing the egg cells.

Fertilization combines DNA. The result is a seed with a tiny plant inside. The ovary grows into a fruit to protect the seeds.

Brain Pop Video

Pollination

Pollinators Animals, wind, and water can all

help in the transfer of pollen. We call animals or insects that

transfer pollen from plant to plant "pollinators ".

The flower type, shape, color, odor, nectar, and structure vary by the type of pollinator that visits them.

Wind PollinationSome flowers, such as grasses, do not have brightly colored petals and nectar to attract insects. These flowers are pollinated by the wind.

Flowering plants use:

• the wind• insects • bats • birds• mammals

to transfer pollen from the stamen (male) part of the flower to the stigma (female) part of the flower.

Check Point

• What is pollination?• How do flowering plants depend on other

living things in order to reproduce?• Why are young plants like but not identical to

their parents?

Fertilization• After pollination a flower

becomes fertilized. • Fertilization is when the

female egg cell and the male sperm cell combine.

• A tube containing the male sperm cell grows down the style to reach the ovules in the ovary.

• Inside each ovule is an egg cell.

From flower to fruit

After fertilization, most of the flower parts wither and drop off

except for the ovary.

Inside the ovary, the ovules begin to

develop into seeds.The ovary then grows bigger until it becomes

a fruit.

seeds develop inside the fruit, fruit grows bigger

petals drop off

ovary begins to swell

Seed Dispersal

Seed dispersal is when seeds are

scattered in order for more plants to

grow.

Oh! I get it.

Seed Dispersal

• Seeds can be easily carried by wind, water, or animals.

• Some fruits can be eaten by animals and the seeds are then dispersed.

How do seeds get dispersed from a plant into the ground?

• Some seeds are hidden in the ground by animals such as squirrels as a winter store.

• Some seeds have hooks on them and cling to fur or clothes.

How do birds and animals help seed dispersal?

Birds and animals eat the fruits and excrete the seeds away from the parent plant.

Ways Seeds are Carried Away from a Plant

• Animal-carried • Animal-consumed• Water-borne• Wind-borne• Propelled

Seed Dispersal

Seed Dispersal

Germination

• After the seeds have been dispersed then germination happens.

• Germination is when a plant begins to sprout from a seed.

Germination

Germination is when the seed sprouts roots and shoots.

DO ALL PLANTS MAKE SEEDS TO REPRODUCE?Ferns and Mosses do not grow seeds. Instead they produce spores.

Ferns produce spores

What are spores?

Spores

• Spores are microscopic specks of living material.

• Ferns produce their spores on the undersides of the leaves.

Spores

What are some plants that produce spores?

ferns

mosses

Ferns DO NOT have seeds. Instead, they reproduce with spores. A spore is a tiny part of a fern that can grow into a new plant. Spores DO NOT have a food supply for the young plant like seeds do.

Characteristics of Ferns

• Ferns are plants that reproduce through spores which are found on the underside of leaves.

• Ferns can be found in damp and shady places.

• They have roots, feathery leaves, and underground stems.

Examples of Ferns

This fern has big leaves divided into many smaller parts. It has “dots” on them. The “dots” on the underside of the leaves are cases where spores grow. Spore cases have spores inside them.

Characteristics of Mosses

• Mosses are some of the simplest plants with simple stems and leaves.

• Mosses have spores which can be found inside a capsule.

• The spores are dispersed by the wind.

Plants Respond to

StimuliSC.3.L.14.2 Investigate and

describe how plants respond to stimuli (heat, water, gravity), such as the way plants stems grow toward light and their

roots grow downward in response to gravity.

ESSENTIAL QUESTION

• How Do Plants Respond To Different Changes In Their Environment?

• Think about what plant part is responding and how that change is allowing the plant to adapt and survive.

What is Stimuli?• Stimuli is when a plant responds to its environment.

(Adaptations to its surroundings.)• When plants change how they grow or move it is called

Tropism – growth or movement • Examples are• Plants roots grow towards water (hydrotropism) • Stems grows towards light (phototropism) • A plant grows vertically and roots grow down to the pull of

gravity (gravitropism or also referred to as geotropism.• Plant responding to heat thermotropism

How do plants respond to different stimuli?

Office of Academics - Department of Science

What are the plants doing in each of these pictures??

Light• Some plant parts grow, or turn towards the sun. Plant

parts include leaves, stems, flowers• A plant can take in more light if it faced the sun. • Leaves must take in light to make food for the plant. • Turning towards the sun helps a plant make the food

it needs.

Why do leave and stems of plants often grow upward?

Plants Grow Towards Light

All Plants Respond to the LightPlants need light to grow. To get all the light they need, the plant stem grows towards the light source.

Light

What are the plants doing in these pictures? What is it called?

It’s gravitropism or geotropism!

Gravity• Gravity causes roots to grow downward.

– Growing downward helps roots reach water and nutrients in soil.

– It helps roots to support the plant. (Roots help keep water and wind from carrying the plant way).

• Stems grow upward away from the pull of gravity. – It helps the leaves face the sun and take in

light.

Roots Grow Down• Pea Time Lapse• Bean Seed Time Lapse

Plants Respond to Gravity Too

On its side or upside down. Plants use the force of gravity to get right side up.

Office of Academics - Department of Science

Gravity

What is the plant doing in this picture? What is it called?

It’s hydrotropism!

Water• Roots grow towards water.• Sometimes roots spread out to reach water.

This helps the plant get the water it needs to make food and live.

Plants Grow Towards Water

Water

Heat- Temperature• In places with cold winters, many flowers

bloom in spring.• Some flowers can bloom any time it gets

warm enough.• Some fruits will not get ripe in cool weather.• Many plants stop growing new leaves or

flowers when it gets cold. – Helps them to live without water or enough

sunlight.

Some flowers open during the day and close at night.

• Dandelion• Water Lily • Lotus Flower

Plants need Heat EnergyIn order for seeds to sprout (germinate) they need heat energy and water. Too much or too little heat will not allow the seed to germinate. Once they have sprouted, they need LIGHT and water more so than HEAT so that photosynthesis can then occur in the leaves.

Plants react to cold by folding up to save Heat Energy.

Different plants grow at different temperatures.

Some plants will only grow under the right temperature conditions.

Heat • Plants do have natural systems that respond to heat

problems. Transpiration is a mechanism in plants to cool themselves by “pumping” water out through the leaves for a kind of swamp-cooler effect.

• If temperatures increase chemicals (proteins) inside the plant surround other “proteins” so the plant can keep its shape.

Essential Question: What similarities and differences exist in the

life cycles of Florida plants and animals?

predictable patterns called life cycles. A life cycle is defined as the complete succession of changes undergone by an organism during its life. A new cycle occurs when an identical set of changes is begun.

3. PlantA living organism in the plant kingdom

Plant Life Cycle:

Plants• Plants come from seeds. Each seed contains a tiny plant waiting for the

right conditions to germinate, or start to grow. Seeds wait to germinate until three needs are met: water, correct temperature (warmth), and a good location (such as in soil). During its early stages of growth, the seedling relies upon the food supplies stored with it in the seed until it is large enough for its own leaves to begin making food through photosynthesis. The seedling's roots push down into the soil to anchor the new plant and to absorb water and minerals from the soil. And its stem with new leaves pushes up toward the light. The germination stage ends when a shoot emerges from the soil. But the plant is not done growing. It's just started. Plants need water, warmth, nutrients from the soil, and light to continue to grow.

Photosynthesis

The student will:

• Learn what photosynthesis is and how it helps plants.

• Learn what a plant needs for photosynthesis.

What is photosynthesis?

• Plants make their own food. This process is called photosynthesis.

What is Photosynthesis?

The food making process in green plants that uses sunlight.

What is photosynthesis?

• Process plants use to make their own food• Plants’ leaves contain chlorophyll• Chlorophyll (green color) makes

photosynthesis possible

Where does photosynthesis occur?

• Photosynthesis occurs in the leaves of a plant.

What is needed for photosynthesis to occur?

• Light is needed for photosynthesis to occur. The plant’s leaves use the light to make a sugar called glucose.

Plants make their own food in their leaves using four ingredients:

1. Sunlight from the sun2. Water3. Carbon dioxide (CO2)4. Chlorophyll from the

leaves

How does Photosynthesis work?

The chlorophyll in the leaves captures the sunlight’s energy and along with the water and carbon dioxide plants produce a food called sugar and release oxygen.

How does Photosynthesis work?

Photosynthesis

• Photosynthesis is the process of making food by plants

• The essential ingredients in making this food are sunlight, the chlorophyll that is present in green plants, water and carbon dioxide in the air.

How it All Works Together?In Photosynthesis, a plant produces plant sugar and Oxygen using light energy. The leaves use water and nutrients transported by the Roots and through the Stem, and the Carbon Dioxide from the Leaves and changes them using Light as energy.

Water is taken in through the roots of the plant and transported to the leaves by

the xylem (tubes that carry water) in the stems.

The Carbon dioxide animals breathe out goes into the leaves through the tiny pores called stomata. It then spreads to the cells that contain chlorophyll in the inside layer of the leaf.

The chlorophyll absorbs the sunlight.

The sunlight is combined with water, Carbon Dioxide and nutrients from the soil.

CO2

The chlorophyll processes the ingredients and makes sugar (plant food) and oxygen.

Sugar + Air

O2

Sunlight is used to break down the water in the plant into oxygen which the plant gives off and we use to breathe.

The hydrogen is then used with the carbon dioxide to create the food for the plants and

ultimately food for animals as well.

Why do plants need glucose?

• Glucose is the food for the plant. It gives the plant energy to grow.

How much glucose does a plant make?

• Plants make enough glucose to be used during the night and on cloudy days when they don’t get sunlight. The extra glucose is stored in the plant’s leaves and other parts.

Photosynthesis is necessary not just for plants to make food for themselves, but for animals, including us eventually.

Plants and animals need each other to survive.

Animals including humans make the CO2

(carbon dioxide) plants need.They (the plants) make the O2 (oxygen)

and food we need.

How does photosynthesis help us?

• During the process of photosynthesis, oxygen is produced. We use this oxygen to breathe.

How does photosynthesis work?

Draw an illustration with captions to explain how plants make their own food through Photosynthesis.
