If carbon dioxide is completely removed from a plant’s environment, what would you expect to happen to the plant’s production of high-energy sugars (rate of photosynthesis)?

• Sugar production will likely increase.

• Sugars will not be produced.

• The rate of sugar production will decrease .

• Fewer sugars will be produced at first, but then the plant will recover.

Why does the rate of photosynthesis decrease at high temperatures?

• Enzymes are denatured

• Enzymes do not have enough kinetic energy

What are the bubbles rising in the test tube?

• nitrogen gas

• carbon dioxide gas

• glucose

• oxygen gas
