Photosynthesis

Front

What is photosynthesis?

Back

Photosynthesis is the process by which plants, some bacteria, and some protists convert light energy into chemical energy, producing glucose and oxygen from carbon dioxide and water.

Front

What are the main reactants of photosynthesis?

Back

The main reactants of photosynthesis are carbon dioxide (CO2) and water (H2O).

Front

What are the main products of photosynthesis?

Back

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

Front

Why is sunlight important for photosynthesis?

Back

Sunlight provides the energy needed for the chemical reactions in photosynthesis to occur.

Front

What role do chlorophyll and pigments play in photosynthesis?

Back

Chlorophyll and other pigments absorb light energy, primarily from the sun, which is essential for photosynthesis.

Front

What is the equation for photosynthesis?

Back

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

Front

What is the significance of photosynthesis for life on Earth?

Back

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

Front

What is the difference between photosynthesis and cellular respiration?

Back

Photosynthesis converts light energy into chemical energy (glucose), while cellular respiration breaks down glucose to release energy for cellular activities.

Front

What is the role of stomata in photosynthesis?

Back

Stomata are small openings on the surface of leaves that allow carbon dioxide to enter and oxygen to exit during photosynthesis.

Front

What is phototropism?

Back

Phototropism is the growth of a plant in response to light direction, helping plants maximize light absorption for photosynthesis.
