Sponges
Sponges are the simplest invertebrates. A sponge’s body is like an empty bag with an opening at the
top. A sponge’s body has no symmetry, is hollow, and has no
bones. Its body is made up of two cell layers with a jelly like substance
between the layers. Food and water flow into a sponge’s body through the
holes in the body. Water and waste move out through the hole at the top. A sponge can regenerate a body part
if the part is missing.
Jelly Fish
Its body is like an empty bag.
Its arms give off a poisonous sting.
Food and wastes leave through an opening at the top.
Earthworms are
segmented.
CHARACTERISTICS:
•They are invertebrates.•They have groups of muscle cells.•The digestive tube has an
opening at the front and at the rear.
•They have a head end.•They have body parts that do
certain jobs.
Mollusks have hard shells and soft bodies. You can find snails and clams by water. Snails are often found in gardens.
The clams that used to live in these shells are probably dead! People can eat raw or cooked clams so these little creatures
better run!!!
Spiny skinned animalsYou can identify most Echinoderms by their star design and their spiny skin.

• A habitat is where an animal lives.
• Some animals live on land; some animals live in water.
• Some animals live in the ground and in trees, too.
In the polar regionthere are 6 months of sunlight and 6 months Of darkness. There is no ozone layer. It is cold and windy so the sun is very dangerous.
Polar Region
The woods are a good place for a habitat because all different kinds of animals live in it like the owl and the squirrel. The owl lives in a tree and so does the squirrel. The squirrel makes a nest out of leaves. The owl sleeps all day and hunts all night. There are many more animals that have habitats in the woods.

A desert is a very dry place.Only a small number of species of plants and animals can survive.

Photosynthesis is the process by which plants make food using SUNLIGHT

and
CHLOROPHYLL Photosynthesis takes place in chloroplasts (special structures in leaf cells). The chloraplasts contain chlorophyll (a green pigment that absorbs energy from sunlight).
This photograph of elodea, a water plant, has many green dots visible within the cells.These are the chloroplasts.
CHLOROPLASTS
The absorbed energy is used to join together carbon dioxide and water to form the sugar, glucose, which is the energy source for the whole plant. Oxygen, a waste product, is released into air.
Veins bring water into leaves and transport the glucose produced by photosynthesis to the rest of the plant.
Leaves are the main sites of photosynthesis and have various adaptations for this purpose.
Flat laminae( blades) provide a large surface for absorbing sunlight.
Stomata (pores) in the lower surface of laminae allow gases (carbon dioxide and oxygen) to pass in and out of the leaves.

•Petal - the part of a flower that is usually colored•Sepal leaf - the leaflike part of the flower that protects the growing bud•Pollen - dust-like yellowish powder produced on the stamens.•Pistil - part of a flower that produces seeds.
Anther- the part of a flowerwhich produces pollen.It is the proper sectionof the stamen.
Filament - the anther bearingstalk of a plant’s stamen
Stigma - the part of the femaleorgan of the flower whichcatches the pollen
Ovary- lower part of the pistil in which seeds growOvule- the part of a plant that can develop into a seed
Roots -> Take in water and food (mineral salts) from soil. Anchors plants. The roots of a plant are spread out.
Stem -> "Like a straw", transports water through plant. Raises the height of flowers and leaves. Brings closer to light. Structural. The stem is made up of little tubes.
Leaves -> Different shapes. Almost always green but sometimes covered with another color such as red. Green substance in leaves -> chlorophyll. Leaves make food for the plant. To do this they need the water and mineral salts obtained from the soil. They are carried inside little veins in the leaf. To make food leaves also need sunshine and CO2.
Flowers - > Flowers produce seeds which form new plants.
Space and warmth also needed for a plant to grow.

How is pollen scattered?
• One of the ways is by bees.•Bees land on a flower.• Pollen sticks to them.
When a bee lands on another flower some of the pollen transfers to
the flower and a little bit of the pollen from the flower sticks to the
bee.
.
Another way pollen scatters is by wind. . . . . . . . . . . . .
Moths, humming birds and butterflies can also pollinate a flower.
A NOT SO WELL-KNOWN POLLEN SPREADER
Pollen- A fine yellowish powder in a flower.
Pollination- The movement of pollen to pistils of flowers.
Pistil- The part of a flower that produces seeds.
Stamen- The part of a flower that contains pollen.
Scatter- To separate and send or go in differentdirections.
Petals- One of the parts of a flower that is usually colored.
Wind- A strong current of air.
Nectar- A sweet liquid in many flowers, made into honeyby bees.
Color- An interesting quality or character.
Scent- A smell or odor.
Pollen gives some people hay fever. It helps plants make their seeds.

What part of the plant develops into a seed?
•The seed develops in the pistil.
•Seeds will grow only when pollen from the same kind of the plant reaches the pistil.
•When a pollen grain reaches the pistil of a flower, the pollen begins to form a tube.
•The pollen tube also contains some of the material that is needed for a seed to grow.
•The material from the pollen joins with the material in the ovule, and a new seed begins to grow.
1.) The pollen grain reaches the pistil.
2.) The pollen begins to form a tube.
3.) The pollen tube goes down the long thin part of the pistil.
4.) The pollen tube reaches into the large bottom part of the pistil called the ovary.
LEARN HOW A SEED DEVELOPS STEP BY STEP
5.) Small ovules are growing inside the ovary. Each ovule contains some of the material that is needed to form a seed.
6.) The pollen tube also contains some of the material that is needed for a seedto grow.
7.) When the material in the pollen grain joins with the material in the ovule, a new seed begins to grow. This is called fertilization.
You need wind. You need water.You need insects. You need birds, and bats and other small animals to help pollinate the plant.

Dicots are seeds that have two parts such as a bean seed.The outside covering of a bean seed is soft. It is called the seed coat.It falls off after being soaked in water.The bean seed has a slit down the middle of it. Inside is a tiny plant called the embryo.The cotyledons are the two large parts of the seed that provide food for the seedling while it is growing.Since the bean seed has two parts, it is called dicotyledon or dicot for short.
A corn seed has only one cotyledon which makes it a monocot. It has a seed coat that is hard and does not slip off easily.It remains in one piece and does not split in to two pieces as the bean seed does.One cotyledon called an endosperm surrounds the embryo and provides foodfor the growing plant.A corn seed is a monocotyledon or monocot for short.
