Photosynthesis Pre-Assess/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 and oxygen.

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 photosynthesis.

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 the Calvin Cycle take place?

Back

The Calvin Cycle occurs in the stroma of chloroplasts.

Front

What is the function of ATP in photosynthesis?

Back

ATP (adenosine triphosphate) provides the energy needed for the Calvin Cycle to convert carbon dioxide into glucose.

Front

What is NADPH and its role in photosynthesis?

Back

NADPH (nicotinamide adenine dinucleotide phosphate) is an electron carrier that provides the reducing power for the Calvin Cycle.

Front

What is the significance of the thylakoid membrane?

Back

The thylakoid membrane contains chlorophyll and is the site of the light-dependent reactions of photosynthesis.

Front

What is the equation for photosynthesis?

Back

The equation for photosynthesis is 6CO₂ + 6H₂O + light energy → C₆H₁₂O₆ + 6O₂.

Front

What happens to water molecules during photosynthesis?

Back

Water molecules are split during the light-dependent reactions, releasing oxygen and providing electrons for the electron transport chain.
