What is the primary function of chloroplasts in plant cells?

Back

Chloroplasts are responsible for photosynthesis, converting sunlight into chemical energy.

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.

Front

What are the two main stages of photosynthesis?

Back

The two main stages 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 pigment that absorbs sunlight, primarily in the blue and red wavelengths, and plays a crucial role in converting light energy into chemical energy.

Front

What are electron carriers in photosynthesis?

Back

Electron carriers are molecules that transport high-energy electrons during the light-dependent reactions of photosynthesis.

Front

What is NADP+ and its role in photosynthesis?

Back

NADP+ is an electron carrier that accepts electrons and becomes NADPH, which is used in the Calvin cycle to help convert carbon dioxide into glucose.

Front

What is the significance of the light-dependent reactions?

Back

The light-dependent reactions capture sunlight and convert it into chemical energy in the form of ATP and NADPH.

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.

Front

How do pigments affect photosynthesis?

Back

Pigments absorb specific wavelengths of light, which is essential for capturing energy needed for photosynthesis.

Front

What is the equation for photosynthesis?

Back

6CO2 + 6H2O + light energy -> C6H12O6 + 6O2.
