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 is the main pigment involved in photosynthesis?

Back

Chlorophyll is the main pigment involved in photosynthesis, which absorbs light energy.

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 leaves of plants, specifically in the chloroplasts.

Front

What is the role of sunlight in photosynthesis?

Back

Sunlight provides the energy needed to drive the chemical reactions that convert carbon dioxide and water into glucose and oxygen.

Front

What is the chemical equation for photosynthesis?

Back

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

Front

What is the role of water in photosynthesis?

Back

Water is a reactant in photosynthesis and is split during the light-dependent reactions to release oxygen and provide electrons.

Front

What are stomata?

Back

Stomata are small openings on the surface of leaves that allow gases (carbon dioxide and oxygen) to enter and exit the leaf.

Front

How does carbon dioxide enter the plant?

Back

Carbon dioxide enters the plant through the stomata during the process of photosynthesis.

Front

What happens to oxygen produced during photosynthesis?

Back

Oxygen produced during photosynthesis is released into the atmosphere as a byproduct.
