THE LIFE CYCLE OF FLOWERING PLANTS

Gloria Varela4th Grade

WHAT IS A FLOWERING PLANT?

HOW DO PLANTS GROW?

PARTS OF A FLOWER What are the 3 main parts of flowers?1. Petals2. Stamens – Male reproductive part of a flower

3. Pistil – Female reproductive parts of a flower

PARTS OF A FLOWER

Peduncle – Stalk of a flower Receptacle – Part of a flower stalk where the parts of the flower are attached Sepal – Outer parts of the flower that enclose a developing bud Petal – Parts of a flower that are often conspicuously colored Stamen – Pollen producing part of a flower Anther – Part of the stamen where pollen is produced Pistil – Ovule producing part of the plant Stigma – Part of the pistil where pollen germinates Ovary – Enlarged basal portion of the pistil where ovules are produced

POLLINATION The act of transferring pollen from the male anther of the stamen to the female stigma

Pollen lands on the female pistil and sperm cells move to the ovary, fertilizing the egg cells

The result is a seed with a tine plant inside The ovary grows into a fruit to protect the seeds Animals, wind and water can all help in the transfer of pollen

Animals or insects that transfer pollen from plant to plant are called “pollinators”

SEEDS 3 main parts1. Seed Coat – protects embryo and guards

endosperm2. Endosperm – stored food3. Embryo – new plant with structures called seed

leaves or cotyledonsHow are seeds carried away from plant?4. Animal carried5. Animal consumed6. Water7. Wind

GERMINATION Seed Germination – the process by which a plant grows from a seed to a plant

What do seeds need to sprout?1. Water2. Oxygen3. Proper temperature4. Some require light
