Photosynthesis

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 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 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 reactants of photosynthesis?

Back

The reactants of photosynthesis are carbon dioxide (CO2) and water (H2O).

Front

What is the main product of photosynthesis?

Back

The main products of photosynthesis are glucose (C6H12O6) and oxygen (O2).

Front

What is the significance of stomata in photosynthesis?

Back

Stomata are small openings on the surface of leaves that allow for the exchange of gases, such as carbon dioxide entering and oxygen exiting.

Front

How does light intensity affect photosynthesis?

Back

Increasing light intensity boosts the rate of photosynthesis up to a certain point, after which it levels off.

Front

What is the function of guard cells?

Back

Guard cells surround stomata and control their opening and closing, regulating gas exchange and water loss.

Front

What is the role of water in photosynthesis?

Back

Water is a reactant in photosynthesis and is split during the light-dependent reactions to release oxygen and provide electrons.

Front

What is the Calvin cycle?

Back

The Calvin cycle is the light-independent stage of photosynthesis where carbon dioxide is fixed into glucose using ATP and NADPH produced in the light-dependent reactions.
