Plant ReproductionBy:

Kris D. & Alyssa M.

Vocabulary

• Ovule- Contains the female sex cells

• Pollen Grain- Contains the male sex cells

• Pollen Tube- Acts as a conduit to bring male sex cells to the ovarys

• Anther- were the pollen develops

Vocabulary Cont.

• Carpel- leaves that cover the ovules

• Filament- Supports the anther

• Ovary- female organ of a flower

• Petal- Modified leaves that surround the reproductive parts of the

flower

Vocabulary Cont.

• Pistil- Female reproductive part of the flower

• Polar Nuclei- Two female haploid nuclei in the embryo sac

• Receptacle- Is the part of the stem where the bud forms

• Sepal- The outer leaves of the flower that protects the flower from

clod or injuries

Vocabulary Cont.

• Stamen- Pollen producing part of a flower

• Stigma- The part if the flower the reviving pollen during pollination

• Style- Supports the ovule

• Epicotyl- The part of seed that will become the plant

Vocabulary Cont.

• Hilum- Scar where the seed was attached to the seed vessel

• Hypocotyl- Stem of the germinating seed

• Plumule- Embryonic leaves

• Radicle- Embryonic root of the plant

• Seed Coat- hard outer layer that protects the seed during germination

Parts of a flower

• Pistil • Stigma • Style • Ovule

• Function • Where the female sex cells are made, fertilized, and mature

Parts Cont.

• Stamen• Where pollen grains are made

• Anther • Where male sex cells are made

• Filament• Long thin structure that supports an Anther

Parts Cont.

• Sepal • Leaf like structure that encloses the bud of a flower

• Carpels• Female reproductive organ of a flower consisting of the stigma, style, and

ovary

Rings of petals

1. Sepals 2. Petals 3. Stamens 4. Ovary

Being a successful Reproducer

• Adaptations for reproduction• Bright colors • Scent• Shape and size

Why are these adaptations useful?

• Used to attract animals for pollination • Bees• Birds • Flies• Small rodents

Double Fertilization

• Double Fertilization- process involves the joining of a female sex cell with two male sex cells• Endosperm- the part of the seed that acts as a food store for the

developing plant embryo

Step 1

• Pollen grain adheres to the stigma • Pollen grain takes in moisture and begins to germinate forming a

pollen tube • Pollen tube extends down toward the ovary through the style • Tip of the pollen tube enter the ovary and penetrates through the

micropyle opening in the ovule• Release the two sperm in the ovule

Step 2

• One sperm fertilizes the egg • One sperm combines with the two polar nuclei• Haploid egg and sperm from the diploid zygote• Two haploid polar nuclei and the egg form a triploid nucleus• Some may form polyploidy

• Then develop into the endosperm

Fruit

• Fruit- sweet and fleshy product of a tree or other plant that contains seed and can be eaten as food • Made in ovaries of plant• Made of maternal tissue

Purpose

• Protect seed • Delays sprouting until right conditions are available• Dispersal

Types of Fruit

• Simple• One ovary in one flower formed one pistol

• Examples• Peas• Corn• Wheat• Cherry• Tomato • Apple

Types of Fruit

• Aggregate• Formed from several pistils of a signal flower

• Examples• Raspberries• Strawberries

Types of Fruit

• Multiple • Formed from several flower all growing together

• Examples• Pineapple• Fig

Parts of the fruit

Dispersal

• Wind picks up seed and moves them the different areas• Example of plant that use this are • Orchids • Dandelions

Dispersal

• Animals eat fruit• Seeds pass unharmed through animals digestive system• Examples of plants that use this are• Date • Sunflowers• Raspberry

Dispersal

• Water • The seeds float and are then carried by the water with the current

until the wash a shore and start to grow• Examples of plants that use this are• Yellow Flag• Foxglove • Willow

Dispersal

• Gravity• Some have a hard outer shell and when they hit the ground they roll

away form the parent • If they have soft skins when they fall the will crack open and the

individual seeds my be scattered • After falling they use animals to finish the job • Examples of plant that use this are• Passion fruit• Canna • Salvia

Monocot Seeds

• Only one seed leaf inside the seed coat because they do not have the endosperm to feed the new plant

Germination- monocots

• Single cotyledon stays below ground and within the seed where it digests the endosperm and transfers the stored energy to the developing plant• The radical portion of the plant is aborted and only fibrous,

adventitious roots are produced

Dicot seeds

• Two seed leaves inside the seed coat because they contain the endosperm to feed the plant

Germination-Dicots

• The cotuledons are well developed and absorb and store nutritive tissue from the endosperm of the seed then they are often pushed up out of the soil and serve as the plants first leaves
