Photosynthesis Bio CFA

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 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 light-independent reactions (Calvin cycle).

Front

Where does photosynthesis occur in plant cells?

Back

Photosynthesis occurs in the chloroplasts of plant cells.

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, and oxygen is released as a byproduct.

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 stomata in plants?

Back

Stomata are small openings on the surface of leaves that allow for gas exchange; they enable plants to take in carbon dioxide and release oxygen.

Front

How does water contribute to photosynthesis?

Back

Water is split during the light-dependent reactions, providing electrons and protons, and releasing oxygen as a byproduct.

Front

What is the equation for photosynthesis?

Back

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