FlowersTheir main jobs for the plant

are:•Develop into seeds & fruits

• = Sexual reproduction•Reproduce the plant•Attract pollinators

3 Stages of Plant Growth

Stages of growth1. Juvenile - when a plant first

starts to grow from a seed.2. Reproductive – when plant

produces flowers, seeds and fruits (any plant with flowers)

3. Dormant – when a plant rests or grows very little if any.

Flowers -

Develop into seeds & fruit1. Sepals - Green parts that cover &

protect flower bud before it opens and are at the base of the flowers once blooming

Sepals

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

2. Petals

3. Stamen - the male flower part that includes 2 parts:

1.Filament - short stalk that holds up the anther so the bees can get it2. Anther - a sac-like

structure that contains pollen (the male sex cells or gametes)

See the pollen???

Anther + Filament = Stamen

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

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!

2) Ovary: holds the ovules or future seeds

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 ovulesStyle

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

Female parts

Complete flower - Has both male & female parts

Incomplete flower - Has only male or

female parts

Pollination - the transfer of pollen from the anther to the stigma of the plant.

Flower Power!!

In groups of 2, use your notes to properly create an anatomically correct flower out of playdough then label the parts on your desk with a dry erase marker.

Take a picture with your phone and then clean it up!
