Question 1 (1 point)
What would happen if a plant could carry out photosynthesis, but not respiration?
Question 1 options:
It would have no food.
It would have too much water.
It would be unable to capture the energy in sunlight.
It could make food but not break it down for energy.
Question 2 (1 point)
During photosynthesis, the following reaction takes place:
carbon dioxide + water + light energy → sugar + oxygen
During cellular respiration, the following reaction takes place:
sugar + oxygen → carbon dioxide + water + chemical energy
Given this information, how are photosynthesis and cellular respiration related?
Question 2 options:
The products of photosynthesis are the reactants of cellular respiration.
Photosynthesis and cellular respiration both start with the same materials.
Photosynthesis and cellular respiration both produce the same materials.
The same type of energy is found in both photosynthesis and cellular respiration.
Question 3 (1 point)
What process controls water loss by the plant, so that the plant will not wither up and die?
Question 3 options:
Respiration
Transpiration
Restoration
Photosynthesis
Question 4 (1 point)
Plants must break down the sugar in cells to obtain energy from the food that is produced. What is this process called?
Question 4 options:
Respiration
Transpiration
Restoration
Photosynthesis
Question 5 (1 point)
Which equation correctly describes photosynthesis?
Question 5 options:
water + sugar + oxygen → carbon dioxide + chlorophyll
sunlight + water + carbon dioxide → oxygen + sugar
sunlight + sugar → water + oxygen
carbon dioxide + oxygen → water + sugar + sunlight
Question 6 (1 point)
Which statement is a correct description of the processes of respiration and transpiration in a plant?
Question 6 options:
Transpiration is when the plant loses water through its leaves. Respiration is when the plant breaks down the sugar in its cells to release energy.
Transpiration is when the plant pulls water into its roots. Respiration is when the plant breathes.
Transpiration is when the plant grows over time. Respiration is when the plant breaks down the sugar in its roots.
Transpiration is when the plant produces buds. Respiration is when the plant dies.

Question 10 (1 point)
What part of the chloroplasts helps to absorb light in order for the plant to make its own food?
Question 10 options:
chlorophyll
stomata
guard cells
photosynthotons
