Flowers Their main jobs for the plant are: Develop into seeds & fruits
= Sexual reproduction Reproduce the plant Attract pollinators
2
3 Stages of Plant Growth Stages of growth
Juvenile - when a plant first starts to grow from a seed. Reproductive – when plant produces flowers, seeds and fruits (any plant with flowers) Dormant – when a plant rests or grows very little if any.
3
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
4
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
5
Filament - short stalk that holds up the anther so the bees can get it
3. Stamen - the male flower part that includes 2 parts: Anther Filament - short stalk that holds up the anther so the bees can get it Filament 2. Anther - a sac-like structure that contains pollen (the male sex cells or gametes)
6
Male parts anther filament Anther + Filament = Stamen See the
pollen???
7
4. Pistil - the female flower part
Female parts: Pistil Male parts: Stamen 1. Ovules - the eggs or female sex cells that become seeds if fertilized
8
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
9
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
10
4. Stigma - sticky part on top of style where insects leave pollen
11
stigma Female parts style ovary
12
Complete flower - Has both male & female parts Incomplete flower - Has only male or female parts
13
All about the birds and bees…
Pollination - the transfer of pollen from the anther to the stigma of the plant.
14
Flower Power!!

Activity In groups of 3-4, use your notes to properly label the plant and flower (now that you know the parts!)
