Unit 6 - Photosynthesis 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 are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose (C6H12O6) and oxygen (O2).

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a green pigment found in the chloroplasts of plants that absorbs light energy, primarily from the sun, to drive the photosynthesis process.

Front

What are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the light-dependent reactions and the Calvin cycle (light-independent reactions).

Front

Where do the light-dependent reactions occur?

Back

The light-dependent reactions occur in the thylakoid membranes of the chloroplasts.

Front

What is the Calvin cycle?

Back

The Calvin cycle is a series of biochemical reactions that take place in the stroma of chloroplasts, where carbon dioxide is converted into glucose using ATP and NADPH produced in the light-dependent reactions.

Front

What is the significance of ATP in photosynthesis?

Back

ATP (adenosine triphosphate) is the energy-carrying molecule produced during photosynthesis that provides the energy needed for various cellular processes, including the Calvin cycle.

Front

What is the role of guard cells in plants?

Back

Guard cells regulate the opening and closing of stomata, controlling gas exchange and water loss in plants.

Front

How does water contribute to photosynthesis?

Back

Water (H2O) is a reactant in photosynthesis that is split during the light-dependent reactions to release oxygen and provide electrons for the formation of ATP and NADPH.

Front

What happens to carbon dioxide during photosynthesis?

Back

Carbon dioxide (CO2) is absorbed from the atmosphere and used in the Calvin cycle to produce glucose.
