Nutrition & Transport in Plants

There are more chloroplasts in the palisade mesophyll cells than in spongy mesophyll cells.

• True
• False

The lamina is broad to increase surface area for maximum absorption of light energy.

• True
• False

The thin film of moisture on the surfaces of mesophyll cells allow glucose to dissolve in it to aid faster rate of diffusion of glucose.

• True
• False

Stomata open to allow gas exchange to take place during photosynthesis. 

• True
• False

The equation for photosynthesis is

• oxygen + water --> glucose + carbon dioxide
• oxygen + glucose --> carbon dioxide + water
• carbon dioxide + water --> glucose + oxygen
• carbon dioxide + glucose --> oxygen + water

Chlorophyll traps light energy and converts it to chemical energy during photosynthesis.

• True
• False

Name the limiting factor at X.

• Light intensity
• Temperature
• Carbon dioxide concentration
• Water

Why does temperature have an effect on the rate of photosynthesis?

• Higher temperature allows carbon dioxide to diffuse into the leaves faster.
• Higher temperature allows water to be transported to the leaves faster.
• Higher temperature allows the stomata to open wider.
• Higher temperature allows the enzymes to function better.

• True
• False

• True
• False
