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 (sugar) and oxygen.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a green pigment found in plants 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 in the plant does photosynthesis primarily occur?

Back

Photosynthesis primarily occurs in the leaves of plants, specifically in the chloroplasts.

Front

What is the light-dependent reaction?

Back

The light-dependent reaction is the first stage of photosynthesis where light energy is converted into chemical energy in the form of ATP and NADPH.

Front

What is the Calvin cycle?

Back

The Calvin cycle is the second stage of photosynthesis where ATP and NADPH produced in the light-dependent reactions are used to convert carbon dioxide into glucose.

Front

What is the significance of oxygen in photosynthesis?

Back

Oxygen is a byproduct of photosynthesis, released into the atmosphere, and is essential for the respiration of most living organisms.

Front

What is the equation for photosynthesis?

Back

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

Front

What is the role of water in photosynthesis?

Back

Water is a reactant in photosynthesis that provides electrons and protons, and is split during the light-dependent reactions to release oxygen.
