1 Flower Dissection Activity

2 There are two types of plants……… plants with seeds and plants without seeds.

3 Plants without Seeds MossesLiverworts Ferns Horsetails

4 How do plants reproduce without seeds? Plants without seeds reproduce through spores that are released into the air.

5 Life Cycle of Ferns The spores are both male and female, so reproduction is taking place.

6 There are two types of reproduction. Type one: Requires one cell through divisions of mitosis. Type two: Requires two cells, a male cell and a female cell, each with half the DNA required to make the new organism. Potato Sprouts Flowering plants with seeds

7 Plants with Seeds GymnospermsAngiosperms Pine trees, or conifers, are an example of a plant that reproduces by seeds but without flowers. Poppies are a type of flowering plant that reproduce by seeds made by flowers.

8 Flowering Plants A flowering plant has both male and female parts. The male part is called the stamen. The female part is called the pistil.

9 Stamen: The male structure of a flowering plant **Please write this definition on your worksheet**

10 Anther: the structure located on top of the stamen and carries the pollen

11 Pollen Pollen is a powdery substance, usually orange or yellow in color, that gets carried by pollinators..

12 Pollinators A pollinator is something that moves pollen from the male parts to the female parts. Can you name any other pollinators?

13 **Please write this definition on your worksheet** Filament: a thread-like part that holds up the anther

14 **Please write this definition on your worksheet** Pistil: the female structure of a flowering plant

15 **Please write this definition on your worksheet** Stigma: the sticky surface on the top of the pistil; it traps and holds the pollen

16 **Please write this definition on your worksheet** Style: the tube-like structure that holds up the stigma

17 **Please write this definition on your worksheet** Ovary: the plant part at the bottom of the flower that has ovules inside (this turns into the fruit and seeds we eat)

18 **Please write this definition on your worksheet** Petal: the colorful flower parts that surround the reproductive structures

19 **Please write this definition on your worksheet** Sepal: the green petal-like parts at the base of the flower; they help protect the bud when it develops

20 **Please write this definition on your worksheet** Perfect: flowers that have both male and female parts (ex. Roses, lilies, and pea plants)

21 **Please write this definition on your worksheet** Pollination: when pollen moves from the male parts to the female parts Watch a bee pollinate a passion flower at

22 Illustrate the Pollination Process and illustrate what you see. 1.First, draw two flowers and label the parts of the male and female structures. 2. Then, watch the pollination animation at

23 Good-bye!
