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

Where does the light-dependent reaction of photosynthesis occur?

Back

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

Front

What is the main purpose of the light-dependent reactions?

Back

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

Front

What is the stroma?

Back

The stroma is the fluid-filled space inside the chloroplast where the light-independent reactions (Calvin Cycle) take place.

Front

What are thylakoids?

Back

Thylakoids are membrane-bound compartments inside chloroplasts that contain chlorophyll and are the site of the light-dependent reactions.

Front

What is chlorophyll?

Back

Chlorophyll is a green pigment found in plants that absorbs light energy, primarily from the sun, to drive photosynthesis.

Front

What is the Calvin Cycle?

Back

The Calvin Cycle is the series of biochemical reactions that occur in the stroma of chloroplasts during the light-independent stage of photosynthesis, where carbon dioxide is converted into glucose.

Front

What role does carbon dioxide play in photosynthesis?

Back

Carbon dioxide is a raw material used by plants during the light-independent reactions to produce glucose.

Front

What are the products of the light-dependent reactions?

Back

The products of the light-dependent reactions are ATP, NADPH, and oxygen.

Front

What is the significance of photosynthesis for life on Earth?

Back

Photosynthesis is crucial for life on Earth as it produces oxygen and organic compounds that serve as food for most living organisms.
