Define spongy mesophyll.

Define stomata.

Define guard cells.

What is the function of the waxy cuticle?

What does the xylem transport, and how does this help the leaf?

What does the phloem transport?

Why is the upper epidermis transparent?

Most plants have more stomata on the     surface of the leaf.

How is the palisade mesophyll adapted for photosynthesis?

The waxy      reduces water loss from the upper surface of the leaf.

What is the role of the air spaces in the spongy mesophyll?

True or False? Guard cells can close the stomata to reduce water loss.

Define the vascular bundle.

What is the function of a leaf?

Give two ways a leaf is adapted for photosynthesis.

Why do leaves have a large surface area?

Why are leaves thin?

A leaf's large      area maximises the absorption of light for photosynthesis.

True or False? Being thin helps carbon dioxide diffuse quickly to the photosynthesising cells.

The leaf is a plant     adapted to carry out photosynthesis.

How does a leaf's shape help carbon dioxide reach the photosynthesising cells?
