Photosynthesis

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy stored in glucose. It occurs mainly in the chloroplasts of plant cells.

Front

What is the primary pigment involved in photosynthesis?

Back

Chlorophyll is the primary pigment involved in photosynthesis, responsible for absorbing light energy.

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 is the role of carbon dioxide in photosynthesis?

Back

Carbon dioxide is one of the raw materials used in photosynthesis. Plants absorb CO2 from the atmosphere and use it to produce glucose.

Front

What is the role of water in photosynthesis?

Back

Water is another raw material for photosynthesis. It is split during the light-dependent reactions to release oxygen and provide electrons for the process.

Front

What is the overall equation for photosynthesis?

Back

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

Front

What is the function of stomata in plants?

Back

Stomata are small openings on the surface of leaves that allow for gas exchange, enabling the intake of carbon dioxide and the release of oxygen.

Front

What is ATP and its role in photosynthesis?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, produced during the light-dependent reactions of photosynthesis and used in the Calvin cycle.

Front

What is the significance of the light-dependent reactions?

Back

The light-dependent reactions capture light energy and convert it into chemical energy in the form of ATP and NADPH, which are used in the Calvin cycle.

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.
