The table shows different conditions that a plant was grown in. Which row shows the conditions that would result in the fastest rate of photosynthesis?

• A
• B
• C
• D

During the day, what would be the correct movement of gases into and out of a leaf?

• Carbon dioxide into the leaf and oxygen out of the leaf
• Carbon dioxide and oxygen both out of the leaf
• Carbon dioxide and oxygen both into the leaf
• Oxygen into the leaf and carbon dioxide out of the leaf

The graph shows the rate of photosynthesis over time. What is the factor limiting photosynthesis at point X?

• Carbon dioxide concentration
• Light intensity
• Concentration of chlorophyll in the leaves
• Temperature

The graph shows the rate of photosynthesis and the rate of respiration in a plant as light intensity increases.Which statement is true at point X?

• No carbon dioxide is being produced.
• The rate of photosynthesis is increasing but respiration has stopped.
• The rate of photosynthesis and the rate of respiration are both increasing.
• The production of carbon dioxide and oxygen will be equal.

A plant is growing in a dense forest early in the morning.What factor or factors would be limiting photosynthesis?

• Light intensity only
• Temperature and light intensity
• Temperature only
• Carbon dioxide concentration and light intensity

Which statement about processes that occur in plants is false?

• Photosynthesis releases energy.
• Plants produce both carbon dioxide and oxygen.
• Not all of the glucose produced in photosynthesis is used in respiration.

What is the correct word equation for aerobic respiration?

• Glucose + Oxygen + Water --> Carbon dioxide
• Glucose + Oxygen --> Carbon dioxide + water
• Glucose + carbon dioxide --> Water + oxygen
• Carbon dioxide + water --> Glucose + oxygen
