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 two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the Light Dependent Reactions and the Light Independent Reactions (Calvin Cycle).

Front

Where does photosynthesis occur in plants?

Back

Photosynthesis occurs primarily in the chloroplasts of plant cells.

Front

What is the role of chlorophyll in photosynthesis?

Back

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

Front

What are the products of the Light Dependent Reactions?

Back

The products of the Light Dependent Reactions are ATP (adenosine triphosphate), NADPH (nicotinamide adenine dinucleotide phosphate), and oxygen.

Front

What is the Calvin Cycle?

Back

The Calvin Cycle, also known as the Light Independent Reactions, is the stage of photosynthesis where carbon dioxide is used to produce glucose.

Front

What gas is taken in by plants during photosynthesis?

Back

Plants take in carbon dioxide (CO2) from the atmosphere during photosynthesis.

Front

What is the significance of oxygen in photosynthesis?

Back

Oxygen is a byproduct of photosynthesis, released into the atmosphere during the Light Dependent Reactions.

Front

What is the thylakoid membrane?

Back

The thylakoid membrane is the site of the Light Dependent Reactions in chloroplasts, where light energy is converted into chemical energy.

Front

What is the stroma in chloroplasts?

Back

The stroma is the fluid-filled space in chloroplasts where the Calvin Cycle takes place.
