1.
There are more chloroplasts in the palisade mesophyll cells than in spongy mesophyll cells.
a)
True
b)
False
2.
The lamina is broad to increase surface area for maximum absorption of light energy.
a)
True
b)
False
3.
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.
a)
True
b)
False
4.
Stomata open to allow gas exchange to take place during photosynthesis.
a)
True
b)
False
5.
The equation for photosynthesis is
a)
oxygen + water --> glucose + carbon dioxide
b)
oxygen + glucose --> carbon dioxide + water
c)
carbon dioxide + water --> glucose + oxygen
d)
carbon dioxide + glucose --> oxygen + water
6.
Chlorophyll traps light energy and converts it to chemical energy during photosynthesis.
a)
True
b)
False
7.
Name the limiting factor at X.
a)
Light intensity
b)
Temperature
c)
Carbon dioxide concentration
d)
Water
8.
Why does temperature have an effect on the rate of photosynthesis?
a)
Higher temperature allows carbon dioxide to diffuse into the leaves faster.
b)
Higher temperature allows water to be transported to the leaves faster.
c)
Higher temperature allows the stomata to open wider.
d)
Higher temperature allows the enzymes to function better.
9.
Excess glucose is converted to glycogen for storage in plants.
a)
True
b)
False
10.
Glucose is converted to starch for transport in plants.
a)
True
b)
False
11.
Xylem is a long, hollow tube without any protoplasm to provide mechanical support to the plant.
a)
True
b)
False
12.
Phloem is living due to the presence of companion cells.
a)
True
b)
False
13.
Transpiration is the loss of water through the stomata of the leaves.
a)
True
b)
False
14.
Translocation is the transport of manufactured food by the phloem.
a)
True
b)
False
15.
Increasing humidity decreases the rate of transpiration as the water potential of the surrounding is higher than the sub-stomatal spaces.
a)
True
b)
False
Reset
