2 Flowers Their main job for the plant is: Develop into seeds & fruits = Sexual reproduction Reproduce the plant.

3 3 stages of plant growth Stages of Growth 1. Juvenile—when plant first starts to grow from a seed. 2. Reproductive—when plant produces flowers, seeds and fruits (any plant with flowers) 3. Dormant—when plant rests or grows very little if any.

4 Flowers - Develop into seeds & fruit 1. Sepals -Green parts that cover & protect flower bud before it opens and are at the base of the flowers once blooming Sepals

5 2. Petals Are really leaves that are modified to attract insects for flower pollination, the pretty part we call flowers. They are bright & colorful to attract birds & bees

6 3. Stamen - the male flower part that includes 2 parts: 1.Filament - short stalk that holds up the anther so the bees can get it 2. Anther - a sac-like structure that contains pollen (the male sex cells or gametes) Filament Anther

7 Male parts anther filament See the pollen??? Anther + Filament = Stamen

8 4. Pistil - the female flower part 1. Ovules - the eggs or female sex cells that become seeds if fertilized A) Female parts: Pistil B) Male parts: Stamen

9 2) Ovary: holds the ovules or future seeds If ovules are fertilized, the ovary becomes a fruit or seed coat. So when you eat a fruit, it is the ovary of the flower! Ovary

10 Pistil (continued) 3. Style – long tube that holds up the stigma & connects it to the ovary. Pollen travels down this tube to get to the ovules Style

11 4. Stigma - sticky part on top of style where insects leave pollen Stigma

12 stigma style ovary Female parts

13 Complete flower - Has both male & female parts Incomplete flower - Has only male or female parts

14 All about the birds and bees… Pollination - the transfer of pollen from the anther to the stigma of the plant.
