PARTS OF A FLOWER
What are the 3 main parts of flowers?
1. Petals
2. 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 parts
1. Seed Coat – protects embryo and guards endosperm
2. Endosperm – stored food
3. Embryo – new plant with structures called seed leaves or cotyledons
How are seeds carried away from plant?
4. Animal carried
5. Animal consumed
6. Water
7. Wind

GERMINATION
Seed Germination – the process by which a plant grows from a seed to a plant
What do seeds need to sprout?
1. Water
2. Oxygen
3. Proper temperature
4. Some require light
