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 sunlight.

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose (sugar) and oxygen.

Front

What is the equation for photosynthesis?

Back

The equation for photosynthesis is: CO₂ + H₂O (with energy from the sun) → O₂ + C₆H₁₂O₆ (glucose).

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 are autotrophs?

Back

Autotrophs are organisms that can produce their own food through photosynthesis or chemosynthesis, such as plants and some bacteria.

Front

What are heterotrophs?

Back

Heterotrophs are organisms that cannot produce their own food and must consume other organisms for energy, such as animals and fungi.

Front

What is the role of chloroplasts in photosynthesis?

Back

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

Front

What is the significance of oxygen produced during photosynthesis?

Back

Oxygen produced during photosynthesis is essential for the survival of aerobic organisms, including humans, as it is used in cellular respiration.

Front

How does temperature affect the rate of photosynthesis?

Back

The rate of photosynthesis increases with temperature up to a certain point, after which it may decrease if the temperature is too high.
