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 role of chlorophyll in photosynthesis?

Back

Chlorophyll is a green pigment found in plants that absorbs light energy, primarily from the blue and red wavelengths, and reflects green light.

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 produced during the light-dependent reactions?

Back

The light-dependent reactions produce ATP (adenosine triphosphate), NADPH, and oxygen.

Front

What is the main purpose of the Calvin Cycle?

Back

The main purpose of the Calvin Cycle is to convert carbon dioxide and other compounds into glucose using the energy from ATP and NADPH.

Front

What is stroma in the context of photosynthesis?

Back

Stroma is the gel-like fluid that surrounds the thylakoids in chloroplasts, where the light-independent reactions (Calvin Cycle) take place.

Front

What are stomata?

Back

Stomata are small openings on the surface of leaves that allow for gas exchange, enabling carbon dioxide to enter and oxygen to exit.

Front

How does water contribute to photosynthesis?

Back

Water is a reactant in photosynthesis; it is split during the light-dependent reactions to release oxygen and provide electrons.

Front

What is the significance of light in photosynthesis?

Back

Light provides the energy needed to drive the chemical reactions in photosynthesis, particularly in the light-dependent reactions.
