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 is the chemical formula for water?

Back

H₂O

Front

What is the chemical formula for glucose?

Back

C₆H₁₂O₆

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose and oxygen.

Front

What role does chlorophyll play in photosynthesis?

Back

Chlorophyll is a pigment found in plants that absorbs light energy, primarily from the red and blue wavelengths, to facilitate 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

What is the significance of the light-dependent reactions?

Back

The light-dependent reactions convert solar energy into chemical energy in the form of ATP and NADPH, and produce oxygen as a byproduct.

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.

Front

How does carbon dioxide concentration affect photosynthesis?

Back

Increasing carbon dioxide concentration generally increases the rate of photosynthesis, up to a certain point.

Front

What environmental factors can affect the rate of photosynthesis?

Back

Factors include light intensity, carbon dioxide concentration, temperature, and water availability.
