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

Where does the light-dependent reaction take place?

Back

The light-dependent reaction takes place in the thylakoid membrane of chloroplasts.

Front

What are the main products of the light-dependent reactions?

Back

The main products of the light-dependent reactions are oxygen and ATP.

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 photosynthesis.

Front

Where are chloroplasts located in a plant?

Back

Chloroplasts are primarily located in the leaves of plants.

Front

What is the Calvin Cycle?

Back

The Calvin Cycle is a series of biochemical reactions that occur in the stroma of chloroplasts, where carbon dioxide is converted into glucose using ATP and NADPH produced in the light-dependent reactions.

Front

What is the ultimate source of energy for living things?

Back

The ultimate source of energy for living things is the Sun.

Front

What is the significance of water in photosynthesis?

Back

Water is essential in photosynthesis as it is split during the light-dependent reactions to release oxygen and provide electrons for the formation of ATP.

Front

What is the equation for photosynthesis?

Back

The equation for photosynthesis is: 6CO2 + 6H2O + light energy → C6H12O6 + 6O2.

Front

What are thylakoids?

Back

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