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 main products of photosynthesis?

Back

The main products of photosynthesis are glucose (a sugar) and oxygen.

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 blue and red wavelengths, to drive the photosynthesis process.

Front

What are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the light-dependent reactions and the Calvin cycle (light-independent reactions).

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

During the light-dependent reactions, ATP, NADPH, and oxygen are produced.

Front

What is the Calvin cycle also known as?

Back

The Calvin cycle is also known as the light-independent reactions or dark reactions.

Front

What is the primary function of the Calvin cycle?

Back

The primary function of the Calvin cycle is to produce simple sugars (glucose) from carbon dioxide.

Front

What is the source of the carbon dioxide used in photosynthesis?

Back

The source of carbon dioxide used in photosynthesis is the atmosphere.

Front

What is the significance of water in photosynthesis?

Back

Water is essential for photosynthesis as it provides electrons and protons, and it is the source of the oxygen released during the process.
