Photosynthesis and Cellular Respiration

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 are the two main stages of photosynthesis?

Back

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

Front

Where does photosynthesis occur in plant cells?

Back

Photosynthesis occurs in the chloroplasts of plant cells.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a green pigment that absorbs light energy, primarily from the sun, which is essential for the photosynthesis process.

Front

What gas is taken in by plants during photosynthesis?

Back

Plants take in carbon dioxide during photosynthesis.

Front

What is the main product of photosynthesis?

Back

The main product of photosynthesis is glucose.

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

What is the relationship between photosynthesis and cellular respiration?

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 ATP and why is it important?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, providing energy for various cellular processes.

Front

What happens to the rate of photosynthesis as light intensity increases?

Back

As light intensity increases, the rate of photosynthesis generally increases until it reaches a saturation point.
