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 in the form of glucose, using carbon dioxide and water.

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose and oxygen.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is the pigment in chloroplasts that absorbs light energy, primarily in the blue and red wavelengths, and is essential for the process of photosynthesis.

Front

What are the two stages of photosynthesis?

Back

The two stages of photosynthesis are the light-dependent reactions and the light-independent reactions (Calvin cycle).

Front

Where does photosynthesis occur in plants?

Back

Photosynthesis primarily occurs in the leaves of plants, specifically in the chloroplasts found in the palisade layer.

Front

What is the palisade layer?

Back

The palisade layer is a layer of tightly packed cells in the leaf that contains chloroplasts and is the main site of photosynthesis.

Front

How do plants absorb water for photosynthesis?

Back

Plants absorb water through their roots, which then travels up the stem to the leaves where photosynthesis occurs.

Front

What is the significance of NADPH and ATP in photosynthesis?

Back

NADPH and ATP are the two products of the light reactions that provide the energy and reducing power needed for the Calvin cycle to synthesize glucose.

Front

What is the Calvin cycle?

Back

The Calvin cycle is the set of light-independent reactions in photosynthesis that convert carbon dioxide and other compounds into glucose using the energy from ATP and NADPH.

Front

What factors affect the rate of photosynthesis?

Back

The rate of photosynthesis can be affected by light intensity, carbon dioxide concentration, temperature, and the availability of water.
