Leaf Structures 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

The color of leaves help....

• to diffuse gases easily

• to capture light energy

• to transport water efficiently

• to bring 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

Cuticle is the outermost part of leaf structure. what is cuticle made of?

Tick all the features of upper epidermis that helps in the process of photosynthesis.

• having a transparent color

• having a lot of chloroplast

• do not have chloroplast

• light can easily penetrate the cells

which of the following leaf structure can do photosynthesis maximally?

• spongy mesophyll

• stoma

• guard cell

• palisade mesophyll

tick all the structures in the leaf that have chloroplast.

• stoma

• guard cell

• mesophyll layer

• xylem

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

Stoma is located in the upper epidermis of leaf.

• True

• False

A structure that help closing or opening the stoma to regulate movement of gases is....
