Topic 6 - Plant Structures And Their Functions - Adaptions Of The Leaf

Question 1

What is the function of stomata in leaves?

Answer 1

Stomata allow gas exchange and can close to minimize water loss or open to increase evaporation and transpiration.

Stomata are tiny openings on the leaf surface that regulate gas exchange.

Question 2

What is the significance of chlorophyll in leaves?

Answer 2

Chlorophyll is green and the most efficient color for absorbing light, maximizing light absorption for photosynthesis.

Chlorophyll plays a crucial role in the photosynthetic process.

Question 3

Why are leaves thin?

Answer 3

Leaves are very thin to allow carbon dioxide to travel a short distance to enter the leaf and oxygen to diffuse out easily.

Thin leaves enhance the efficiency of gas exchange for photosynthesis.

Question 4

How does a large surface area benefit leaves?

Answer 4

A large surface area allows the leaf to absorb more light at once, maximizing the rate of photosynthesis.

This adaptation is critical for efficient energy capture.
