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 pigment involved in photosynthesis?

Back

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

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose and oxygen.

Front

What is the role of sunlight in photosynthesis?

Back

Sunlight provides the energy required for the photosynthesis process, enabling plants to convert carbon dioxide and water into glucose.

Front

What is the equation for photosynthesis?

Back

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

Front

What are autotrophs?

Back

Autotrophs are organisms that produce their own food from inorganic substances, primarily through photosynthesis.

Front

What is the role of chloroplasts in photosynthesis?

Back

Chloroplasts are the organelles in plant cells where photosynthesis takes place, containing chlorophyll.

Front

How does carbon dioxide concentration affect photosynthesis?

Back

Increasing carbon dioxide concentration generally increases the rate of photosynthesis, up to a certain point.

Front

What environmental factors can affect the rate of photosynthesis?

Back

Factors include light intensity, carbon dioxide concentration, temperature, and water availability.

Front

What is the significance of photosynthesis to life on Earth?

Back

Photosynthesis is crucial as it produces oxygen and organic compounds that are the foundation of the food chain.
