6.14B **Biology Only** -​ ​Extreme Adaptations

Question 1

What adaptations help plants survive in extreme environments?

Answer 1

Plants have specific adaptations that maximize their ability to take in sunlight and carbon dioxide.

Question 2

How does leaf shape and size help desert plants?

Answer 2

Many desert plants do not have leaves or have very small leaves, reducing water loss through transpiration.

Question 3

What is the function of a waxy cuticle on leaves?

Answer 3

A waxy cuticle prevents evaporation of water in environments where water is scarce.

Question 4

What are stomata?

Answer 4

Stomata are small pores on the surface of a leaf that can open and close to regulate water loss and carbon dioxide intake.

Question 5

How do stomata help plants in extreme environments?

Answer 5

Stomata can close to prevent water evaporation and open when carbon dioxide is needed for photosynthesis.
