adaptations

Question 1

Leaves are thin

Answer 1

Provides a short diffusion distance for carbon dioxide to reach mesophyll cells and for oxygen to exit

Question 2

Leaves are broad and flat to form a large surface area

Answer 2

Absorbs maximum amount of sunlight for higher rate of
photosynthesis

Question 3

There are a large number of chloroplasts in the tightly packed palisade mesophyll cells
Palisade mesophyll cells are located at the upper part of the leaf

Answer 3

Absorbs maximum amount of sunlight for higher rate of
photosynthesis

Question 4

Upper epidermis and cuticle are transparent

Answer 4

Allows sunlight to pass through and reach mesophyll cells
where photosynthesis takes place

Question 5

Leaves have many stomata

Answer 5

Allows gases to move in and out of leaves

Question 6

Size of each stoma is controlled by a pair of guard cells

Answer 6

Guard cells open the stoma more under sunlight so that more carbon dioxide diffuses in for a higher rate of photosynthesis
