A Day in the Life of a Flower
Flower Function Primary Function: -To attract animals to pollinate the plant and reproduce. This is necessary in order for the species to survive!
Pollination vs. Fertilization There is a difference!!! Pollination is the transfer of pollen grain from the anther to the pistil Fertilization occurs when the sperm joins with the egg in the ovary of the plant
Where do Seeds come from? Seeds are basically enlarged ovules within a plant’s ovary Seeds are formed after fertilization occurs Seeds are what sprouts new plants!!!
Seed Anatomy 1.Seed Coat – protective outer layer 2.Embryo – earliest stage of development for a plant 3.Endosperm (Cotyledon) – food storage tissue that supports development of growing embryo
Seed Anatomy – Part 2 Embryo Endosperm (Cotyledon) Seed Coat
Fruit Formation Question: What enlarges to become the fruit within a plant? Answer: The Ovary!!! Remember: When we eat an apple, we are eating the ovary which surrounds the seeds or core of the apple! Yum!!!
How do Fruits help Seeds? 1.Provide protection for the developing seeds 2.Can help seeds spread
Putting it all together!! Using figure in your book, sketch out the life cycle of a flowering plant Remember to distinguish between what happens with regard to pollination and fertilization
