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 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 chlorophyll in photosynthesis?

Back

Chlorophyll absorbs light energy, primarily from the blue and red wavelengths, and converts it into chemical energy.

Front

What is the equation for photosynthesis?

Back

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

Front

What are the products of photosynthesis?

Back

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

Front

What is the function of NADPH in photosynthesis?

Back

NADPH serves as a reducing agent, providing the necessary electrons for the reduction of carbon dioxide in the Calvin cycle.

Front

What is the function of ATP in photosynthesis?

Back

ATP provides the energy required for various biochemical reactions during the light-independent reactions (Calvin cycle) of photosynthesis.

Front

Why do leaves change color in autumn?

Back

Leaves change color in autumn because chlorophyll breaks down, revealing other pigments such as carotenoids, which produce yellow and orange colors.

Front

What is the significance of the light-dependent reactions?

Back

The light-dependent reactions capture and convert light energy into chemical energy (ATP and NADPH) and produce oxygen as a byproduct.
