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, and releasing oxygen as a byproduct.

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 does photosynthesis occur in plants?

Back

Photosynthesis occurs primarily in the chloroplasts of plant cells.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a green pigment found in chloroplasts that absorbs light energy, primarily from the sun, which is essential for the light-dependent reactions of photosynthesis.

Front

What are the inputs required for photosynthesis?

Back

The inputs required for photosynthesis are carbon dioxide (CO2), water (H2O), and light energy.

Front

What are the products of photosynthesis?

Back

The products of photosynthesis are glucose (C6H12O6) and oxygen (O2).

Front

What occurs during the light-dependent reactions?

Back

During the light-dependent reactions, light energy is captured and converted into chemical energy in the form of ATP and NADPH, and oxygen is released as a byproduct.

Front

What is the Calvin Cycle?

Back

The Calvin Cycle, also known as the light-independent reactions, is the stage of photosynthesis where ATP and NADPH are used to convert carbon dioxide into glucose.

Front

Where do the light-dependent reactions take place?

Back

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

Front

What is the function of ATP in photosynthesis?

Back

ATP serves as a short-term energy carrier that provides energy for various biochemical reactions, including those in the Calvin Cycle.
