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 function 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 the process of 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

Where do the light-dependent reactions occur in the chloroplast?

Back

The light-dependent reactions occur in the thylakoid membranes of the chloroplast.

Front

What is produced during the light-dependent reactions?

Back

The light-dependent reactions produce ATP, NADPH, and oxygen as byproducts.

Front

What is the role of ATP in photosynthesis?

Back

ATP serves as the energy currency of the cell, providing the energy needed for various biochemical reactions, including those in the Calvin cycle.

Front

What is the Calvin cycle?

Back

The Calvin cycle is a series of biochemical reactions that occur in the stroma of chloroplasts, where carbon dioxide is fixed into glucose using ATP and NADPH produced in the light-dependent reactions.

Front

What is the significance of water in photosynthesis?

Back

Water is essential for photosynthesis as it provides electrons and protons for the light-dependent reactions and is a source of oxygen released as a byproduct.

Front

What are the products of the Calvin cycle?

Back

The products of the Calvin cycle include glucose and other carbohydrates, which are used by the plant for energy and growth.

Front

How does carbon dioxide enter the plant?

Back

Carbon dioxide enters the plant through small openings called stomata, located on the leaves.
