1 Flower Dissection Activity Review

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

6 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.

7 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.

8 Stamen: The male reproductive structure of a flowering plant

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

10 Pollen Pollen is the male sex cell that donates half of the DNA to make a seed. It is a powdery substance, usually orange or yellow in color, that gets carried by pollinators.

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

12 Filament: a thread-like part that holds up the anther

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

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

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

16 Ovary: the plant part at the bottom of the flower that has ovules inside (this turns into the fruit and seeds we eat)

17 Ovules: the female sex cells inside the ovary that donate half the DNA to become the seed (They become the seeds when pollinated or fertilized by the pollen.) A baby seed!

18 Petal: the colorful flower parts that surround the reproductive structures

19 Sepal: the green petal-like parts at the base of the flower; they help protect the bud when it develops

20 Perfect: flowers that have both male and female parts (ex. Roses, lilies, and pea plants)

21 Imperfect: flowers with male or female parts (ex- cucumbers, pumpkins, and melons)

22 Pollination: when pollen moves from the male parts to the female parts
