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 (LDR) and the Calvin Cycle (Light Independent Reactions).

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 photosynthesis process.

Front

What are the reactants of photosynthesis?

Back

The reactants of photosynthesis are carbon dioxide (CO2) and water (H2O).

Front

What is produced during the light dependent reactions?

Back

The light dependent reactions produce oxygen (O2), ATP, and NADPH.

Front

Where do the light dependent reactions occur?

Back

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

Front

What is the Calvin Cycle?

Back

The Calvin Cycle is the set of chemical reactions that take place in the chloroplasts during photosynthesis, where ATP and NADPH are used to convert carbon dioxide into glucose.

Front

What is the significance of oxygen produced in photosynthesis?

Back

Oxygen produced during photosynthesis is released into the atmosphere and is essential for the respiration of most living organisms.

Front

How many carbon dioxide molecules are needed to produce one glucose molecule?

Back

It takes six carbon dioxide (CO2) molecules to produce one glucose (C6H12O6) molecule.

Front

What is the main purpose of the light dependent reactions?

Back

The main purpose of the light dependent reactions is to convert light energy into chemical energy in the form of ATP and NADPH.
