Photosynthesis

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 are the main products of photosynthesis?

Back

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

Front

Where does photosynthesis occur in plant cells?

Back

Photosynthesis occurs in the chloroplasts of plant cells.

Front

What are the reactants needed for photosynthesis?

Back

The reactants needed for photosynthesis are water (H2O), carbon dioxide (CO2), and sunlight energy.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a green pigment found in chloroplasts that absorbs light energy, primarily from the sun, which is essential for photosynthesis.

Front

What is the Calvin Cycle?

Back

The Calvin Cycle is a series of biochemical reactions that occur in the chloroplasts during photosynthesis, where carbon dioxide is converted into glucose.

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 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 for life on Earth as it produces oxygen, which is essential for the survival of aerobic organisms, and it forms the base of the food chain.

Front

What factors affect the rate of photosynthesis?

Back

The rate of photosynthesis is affected by light intensity, carbon dioxide concentration, temperature, and the availability of water.
