1. Wake-up Watch in presentation mode! 1.Explain the difference between a gymnosperm and an angiosperm. 1.List the four main groups of plants.

2. Flower Structure There are several videos in these notes. Please watch them. I really think you will enjoy them!! If you are having trouble with the links, copy and paste the address in a different browser.

3. What is a flower? Reproductive structure of Angiosperms (flowering plants)

4. Petals: Attract Pollinators Sepals: First leaves on bud Pistil: Female Stamen: Male Locule: Chamber of Eggs Ovary: Eggs (Ovules)

5. Pistil: Female Stigma: Sticky to attract pollen Style: “Neck” of the Pistil Ovary Eggs/Ovules

8. Stamen: Male Anther: Contains Pollen (Sperm) Filament: Anther Stalk

11. What is pollination? Transfer of pollen from the anther to the stigma of a plant

12. Type of Pollination: Self Pollination Plant fertilizes it own eggs

13. Type of Pollination: Cross Pollination Pollen from one flower fertilizes the egg of another

14. Methods of Cross Pollination 1. Wind: Plant produce lightweight pollen in great numbers with the hopes of landing on another plant of its kind Video LINK #1 Select “Yellow Pollen Coats State” Video Video LINK #2

15. Methods of Cross Pollination 2. Animals: Flowers have bright petals, nectar, and a sweet smell to attract animals. Pollen gets dropped off on animal and they carry to another plant

16. Mutualistic Coevolution Plants and animals have changed (evolved) together over time to create a relationship that is completely depend on each other

17. Example #1 Plant: Corpse flower (Titan Arum) Animal: Flies Flies are attracted to the corpse flower because it smells like rotten meat; pick up the pollen Video LINK

18. Example #2 Plant: Flowers Animal: Bats Bats are attracted to the large, strong smelling flowers Video LINK #1 The flower drops its pollen on the bat which carries it to another flower Video: Planet Earth D esert (23:50)

20. Example #3 Plant: Flowers Animal: Bees Flowers provide bees with nectar and pollen, both of which are a food source.

21. Example #3 Plant: Flowers Animal: Bees In turn the bee helps carry the flowers pollen to other flowers; bees are covered in tiny hairs LINK #1 LINK #2

22. Video Clip: Beauty of Pollination

23. When complete with notes, get the Flower Structure Coloring Activity from the substitute and grab a plastic container with markers and colored pencils. With the time left in class, complete this activity. You need to color, label, and answer the questions. If you complete this activity, turn it into the bin and find something else to work on. If not, this is homework tonight.
