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.

What is autotrophic nutrition?

Back

Autotrophic nutrition is a mode of nutrition in which organisms produce their own food from inorganic substances, primarily through photosynthesis.

What is the role of chloroplasts in photosynthesis?

Back

Chloroplasts are organelles in plant cells where photosynthesis occurs, containing chlorophyll that captures light energy.

Front

What is the equation for photosynthesis?

Back

6CO2 + 6H2O + light energy → C6H12O6 + 6O2 (Carbon dioxide + Water + Light energy → Glucose + Oxygen).

Front

What is the significance of light energy in photosynthesis?

Back

Light energy is essential for photosynthesis as it is converted into chemical energy, which is stored in glucose.

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

What happens during the light-dependent reactions?

Back

During the light-dependent reactions, light energy is captured and used to produce ATP and NADPH, and oxygen is released as a byproduct.

Front

What is the Calvin cycle?

Back

The Calvin cycle is the light-independent stage of photosynthesis where ATP and NADPH are used to convert carbon dioxide into glucose.

Front

How do guard cells regulate water loss in plants?

Back

Guard cells control the opening and closing of stomata, which regulate water loss and gas exchange in plants.

Front

What is the role of carbon dioxide in photosynthesis?

Back

Carbon dioxide is a raw material in photosynthesis, used to synthesize glucose during the Calvin cycle.
