Photosynthesis - Biology

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 formula for photosynthesis?

Back

The formula for photosynthesis is: CO₂ + H₂O → O₂ + C₆H₁₂O₆.

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 do light reactions occur in the plant cell?

Back

Light reactions occur in the thylakoid membranes of chloroplasts.

Front

What is chlorophyll?

Back

Chlorophyll is a green pigment found in plants that absorbs light energy, primarily in the blue and red wavelengths, and reflects green light.

Front

Why do most plants appear green?

Back

Most plants appear green because chlorophyll reflects green light and absorbs other wavelengths.

Front

What is the role of sunlight in photosynthesis?

Back

Sunlight provides the energy needed for the light-dependent reactions of photosynthesis.

Front

What is the significance of water in photosynthesis?

Back

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

Front

What is the role of carbon dioxide in photosynthesis?

Back

Carbon dioxide is a reactant in photosynthesis that is fixed during the Calvin cycle to produce glucose.

Front

What are the products of photosynthesis?

Back

The products of photosynthesis are glucose (C₆H₁₂O₆) and oxygen (O₂).
