Biology 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 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 produced during the light-dependent reactions?

Back

The light-dependent reactions produce ATP, NADPH, and oxygen.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a pigment found in chloroplasts that absorbs light energy, primarily from the sun, which is essential for the photosynthesis process.

Front

What is the Calvin Cycle?

Back

The Calvin Cycle is the light-independent stage of photosynthesis where carbon dioxide is fixed into glucose using ATP and NADPH produced in the light-dependent reactions.

Front

What is the primary gas taken in by plants during photosynthesis?

Back

Carbon dioxide is the primary gas taken in by plants during photosynthesis.

Front

What is ATP and why is it important in photosynthesis?

Back

ATP (adenosine triphosphate) is an energy-carrying molecule that provides energy for various cellular processes, including the Calvin Cycle in photosynthesis.

Front

What is the significance of oxygen in photosynthesis?

Back

Oxygen is a byproduct of the light-dependent reactions of photosynthesis and is released into the atmosphere.

Front

What are thylakoids?

Back

Thylakoids are membrane-bound structures within chloroplasts where the light-dependent reactions of photosynthesis occur.

Front

What is a granum?

Back

A granum is a stack of thylakoids within a chloroplast, where chlorophyll is located and light-dependent reactions take place.
