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.

Front

Where does photosynthesis occur in plant cells?

Back

Photosynthesis occurs in the chloroplasts of plant cells.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is the green pigment in plants that absorbs light energy, which is essential for photosynthesis.

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

What is the chemical equation for photosynthesis?

Back

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

Front

What is the function of stomata in plants?

Back

Stomata are small openings on the surface of leaves that allow for gas exchange; they let carbon dioxide in and oxygen out.

Front

What do autotrophs produce during photosynthesis?

Back

Autotrophs produce glucose and oxygen during photosynthesis.

Front

What is the significance of glucose for plants?

Back

Glucose serves as an energy source for plants and is used to build other organic compounds.

Front

What are heterotrophs?

Back

Heterotrophs are organisms that cannot produce their own food and must consume other organisms for energy.

Front

What is the role of sunlight in photosynthesis?

Back

Sunlight provides the energy needed for the photosynthesis process to convert carbon dioxide and water into glucose.
