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.

Where do the light reactions of photosynthesis occur?

Back

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

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 sun, which is essential for photosynthesis.

What are grana in the context of chloroplasts?

Back

Grana are stacks of thylakoids within the chloroplasts where the light-dependent reactions of photosynthesis take place.

Front

How do high temperatures affect photosynthesis?

Back

High temperatures can slow down photosynthesis because they can denature enzymes that are crucial for the process.

Front

What is the function of stomata in photosynthesis?

Back

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

What is ATP and its role in photosynthesis?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, produced during the light reactions of photosynthesis and used in the Calvin cycle to synthesize glucose.

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

What is the Calvin cycle?

Back

The Calvin cycle is the set of light-independent reactions in photosynthesis that occur in the stroma of chloroplasts, where carbon dioxide is converted into glucose.
