Photosynthesis Review

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 are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose and oxygen.

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 the photosynthesis process.

Front

What are thylakoids?

Back

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

Front

What is the stroma?

Back

The stroma is the fluid-filled space surrounding the thylakoids in chloroplasts where the light-independent reactions (Calvin Cycle) occur.

Front

What is the Calvin Cycle?

Back

The Calvin Cycle is a series of biochemical reactions that take place in the stroma of chloroplasts, where carbon dioxide is converted into glucose using ATP and NADPH.

Front

What is the significance of ATP in photosynthesis?

Back

ATP (adenosine triphosphate) provides the energy required for the Calvin Cycle to synthesize glucose from carbon dioxide.

Front

What is the difference between light-dependent and light-independent reactions?

Back

Light-dependent reactions require light to produce ATP and NADPH, while light-independent reactions (Calvin Cycle) do not require light and use ATP and NADPH to synthesize glucose.

Front

How do plants absorb water?

Back

Plants absorb water through their roots, which then travels up the stem to the leaves.

Front

What is a granum?

Back

A granum is a stack of thylakoids within the chloroplasts, where the light-dependent reactions of photosynthesis occur.
