Gymnosperm 1
What does the term "Gymnosperm" mean?
Naked Seed
This method is how most gymnosperms transfer pollen from male to female cones.
Wind Pollination
What does the term Angiosperm mean?
Covered Seed
Are Angiosperms Vascular?
They are Non-Vascular
Are Gymnosperms Non-Vascular?
NO! They are Vascular
Gymnosperms do not have flowers--instead, their seeds are found in...
Cones!
What are the reproductive structures of Angiosperms?
Stamen = Male Part
Pistil/Carpel = Female Part
Monocot: 1 seed leaf, parallel veins, flower parts in 3, fibrous roots
Dicot: 2 seed leaves, branching/net veins, flower parts in 4s/5s, taproots
What do gymnosperms use for reproduction?
"Flying Seeds" and Pollen
How do we distinguish different conifer species?
Conifers can be distinguished by needle shape, needle arrangement, cone shape, bark, and tree form
Why are angiosperms important?
they provide food, oxygen, medicine, habitats, wood, fibers, and beauty.
What are the four ways seeds are dispersed?
Wind, animals, humans, water, bursting
List eight adaptations that desert plants may have to help them survive in a harsh environment?
Why are Gymnosperms ecologically different?
They are ecologically important because they provide habitats, food, oxygen, erosion control, and carbon storage.
Why are gymnosperms commercially important?
Commercially important because they provide wood/lumber, paper, resin, turpentine, Christmas trees, and some medicines
List angiosperm pollinators as well as the flower type that attracts each pollinator
Bees: bright blue/yellow flowers, sweet smell, nectar.
Butterflies: bright flowers, flat landing spots.
Moths: white/pale flowers, strong smell at night.
Birds/hummingbirds: red or orange tube-shaped flowers.
Bats: large pale flowers, strong smell, open at night.
Flies: flowers that smell rotten or strong.
Wind: small, plain flowers with lots of pollen.
This part of a flower receives pollen and is located at the top of the pistil.
Stigma
How is the process of photosynthesis modified in desert plants compared to plants that do not live in deserts
Desert plants often use CAM photosynthesis. They open stomata at night to take in carbon dioxide, then close stomata during the day to save water while still doing photosynthesis.
