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 primary site of photosynthesis in plant cells?

Back

The primary site of photosynthesis in plant cells is the chloroplast.

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are oxygen and glucose.

Front

What are the reactants required for photosynthesis?

Back

The reactants required for photosynthesis are carbon dioxide and water.

Front

What is the chemical equation for photosynthesis?

Back

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

Front

How do plants and animals interact in terms of gas exchange?

Back

Plants give off oxygen that animals need to breathe, while animals exhale carbon dioxide that plants use for photosynthesis.

Front

What role does sunlight play in photosynthesis?

Back

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

Front

What pigment is primarily responsible for capturing light energy in plants?

Back

Chlorophyll is the pigment primarily responsible for capturing light energy in plants.

Front

Why is photosynthesis important for life on Earth?

Back

Photosynthesis is important because it produces oxygen, which is essential for the survival of most living organisms, and it forms the base of the food chain.

Front

What is the difference between autotrophs and heterotrophs?

Back

Autotrophs are organisms that produce their own food through photosynthesis (like plants), while heterotrophs are organisms that consume other organisms for energy (like animals).
