Photosynthesis and Cellular Respiration Exam Review

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose, using carbon dioxide and water.

Front

What is the primary purpose of photosynthesis?

Back

The primary purpose of photosynthesis is to make glucose, which serves as an energy source for plants and other organisms.

Front

What are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the light reactions and the Calvin cycle.

Front

How does increased carbon dioxide affect the rate of photosynthesis?

Back

Increasing the amount of carbon dioxide generally increases the rate of photosynthesis.

Front

What is the role of light in photosynthesis?

Back

Light provides the energy needed for the light reactions of photosynthesis, which convert solar energy into chemical energy.

Front

What happens to the color of a BTB solution when carbon dioxide is present?

Back

The BTB solution turns yellow in the presence of carbon dioxide, indicating acidity.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

How are photosynthesis and cellular respiration related?

Back

Photosynthesis produces glucose and oxygen, which are used in cellular respiration to produce energy, while cellular respiration releases carbon dioxide and water, which are used in photosynthesis.

Front

What is the effect of light distance on the rate of photosynthesis?

Back

The closer the light source is to the plant, the greater the rate of photosynthesis, up to a certain point.

Front

What is chlorophyll?

Back

Chlorophyll is the green pigment found in plants that absorbs light energy for photosynthesis.
