Leaf Structure and Photosynthesis

Tick all the reasons for having an arrangement of leaves like shown in the picture

• to be efficient in gases diffusion

• to have very large surface area can be exposed to light

• to avoid overlapping between leaves

• to bring water and nutrient close to each cell

Tick all the reasons to have branching of veins in leaf.

• to reduce time needed for diffusion

• to transport water and nutrient close to every cell

• to capture light efficiently

• to ensure light can penetrate the leaf

what is the function of air space in between the spongy mesophyll?

• to easily capture light

• to transport water into mesophyll layer

• to allow the exchange of gases

• to close / open the stoma
