Photosynthesis

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy, usually from the sun, 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 that absorbs sunlight during photosynthesis.

Front

What do plants need for photosynthesis?

Back

Plants need sunlight, carbon dioxide, and water to perform photosynthesis.

Front

Where does photosynthesis primarily occur in plants?

Back

Photosynthesis primarily occurs in the leaves of plants, specifically in the chloroplasts.

Front

What gas do plants take in during photosynthesis?

Back

Plants take in carbon dioxide (CO2) during photosynthesis.

Front

What gas do plants release during photosynthesis?

Back

Plants release oxygen (O2) as a byproduct of photosynthesis.

Front

What is the role of sunlight in photosynthesis?

Back

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

Front

What are stomata?

Back

Stomata are tiny openings on the surface of leaves that allow carbon dioxide to enter and oxygen to exit.

Front

Why are plants considered essential for life on Earth?

Back

Plants are essential because they produce oxygen and serve as the base of the food chain, supporting life for many organisms.

Front

What is the chemical equation for photosynthesis?

Back

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