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, and releasing oxygen as a byproduct.

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?

Back

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

Front

What is the primary function of the light-dependent reactions?

Back

The primary function of the light-dependent reactions is to convert solar energy into chemical energy in the form of ATP and NADPH.

Front

What is produced during the light-dependent reactions?

Back

During the light-dependent reactions, ATP, NADPH, and oxygen are produced.

Front

Where do the light-independent reactions (Calvin cycle) take place?

Back

The light-independent reactions (Calvin cycle) take place in the stroma of the chloroplasts.

Front

What is the main purpose of the Calvin cycle?

Back

The main purpose of the Calvin cycle is to synthesize glucose from carbon dioxide using ATP and NADPH produced in the light-dependent reactions.

Front

What role does chlorophyll play in photosynthesis?

Back

Chlorophyll absorbs sunlight and uses its energy to synthesize carbohydrates from carbon dioxide and water.

Front

What is the significance of NADP+ in photosynthesis?

Back

NADP+ is a carrier molecule that accepts electrons during the light-dependent reactions, becoming NADPH, which is then used in the Calvin cycle.

Front

How does carbon dioxide enter the plant?

Back

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