1. Which of the following statements best describe the difference between angiosperms and gymnosperms?
A. Angiosperms produce cones to protect their seeds; gymnosperm seeds are surrounded by fruit.
B. Gymnosperms include fruit trees and ginkgos; angiosperms include conifers, spruces, and firs
C. Gymnosperms are mostly adapted for wind pollination; angiosperms are mostly adapted for animal pollination.
D. Angiosperms were the first to colonize land; Gymnosperms developed later than the more primitive angiosperms.

2. The outer covering of some land plants that helps slow water loss is called:
A. Chlorophyll
B. Chitin
C. Cuticle
D. Stomata

3. What adaptation of land plants helps it to control gas exchange with the atmosphere?
A. Chitin
B. Cuticle
C. Stomata
D. Chlorophyll

4. A plant that remains low to the ground and grows in moist conditions is most likely what type of plant?
A. Vascular
B. Nonvascular
C. Angiosperm
D. Gymnosperm

5. Terrestrial plants contain lignin to support the plant and vascular tissue to transport water and nutrients through the plant. What are these adaptations in response to?
A. Heat
B. Gravity
C. Dryness
D. Gas exchange

Respuesta :

1) C. Gymnosperms are mostly adapted for wind pollination; angiosperms are mostly adapted for animal pollination. This is the best answer, because the others had the two types reversed. Gymnos have "naked" seeded cones, whereas Angios have seeds protected by fruit. Therefore the Angios relies on animals to eat the fruit and to pollinate, whereas Gymnos relied on wind to pollinate the ground. Gymnos came first on Earth and Angios developed later.

2) C. Cuticle. This is a waxy coating helping to keep water in. The main water losses are via stomata.

3) C. Stomata

4) B. Nonvascular

5) B. Gravity

These answers were explained in the questions that I just answered before. So refer to those for explanations.
