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 Calvin cycle (light-independent reactions).

Front

Where does photosynthesis occur in plants?

Back

Photosynthesis occurs 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 reactants of photosynthesis?

Back

The reactants of photosynthesis are light energy, carbon dioxide (CO2), and water (H2O).

Front

What are the products of photosynthesis?

Back

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

Front

What is the light-dependent reaction?

Back

The light-dependent reaction is the first stage of photosynthesis, occurring in the thylakoid membranes, where light energy is converted into chemical energy (ATP and NADPH) and oxygen is released.

Front

What is the Calvin cycle?

Back

The Calvin cycle is the second stage of photosynthesis, occurring in the stroma of chloroplasts, where ATP and NADPH are used to convert carbon dioxide into glucose.

Front

What is stroma in the context of chloroplasts?

Back

Stroma is the fluid-filled space surrounding the thylakoids in chloroplasts, where the Calvin cycle takes place.

Front

What is the significance of photosynthesis for life on Earth?

Back

Photosynthesis is crucial for life on Earth as it produces oxygen, which is essential for the survival of aerobic organisms, and it forms the base of the food chain by providing energy in the form of glucose.
