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.
Excess glucose is converted to glycogen for storage in plants.
  • True
  • False
Glucose is converted to starch for transport in plants.
  • True
  • False
Xylem is a long, hollow tube without any protoplasm to provide mechanical support to the plant.
  • True
  • False
Phloem is living due to the presence of companion cells. 
  • True
  • False
Transpiration is the loss of water through the stomata of the leaves.
  • True
  • False
Translocation is the transport of manufactured food by the phloem.
  • True
  • False
Increasing humidity decreases the rate of transpiration as the water potential of the surrounding is higher than the sub-stomatal spaces. 
  • True
  • False
