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 main pigment involved in photosynthesis?

Back

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

Front

Which pigment reflects orange and red light?

Back

Carotenoids reflect orange and red light.

Front

What is the equation for photosynthesis?

Back

6CO₂ + 6H₂O → 6O₂ + C₆H₁₂O₆.

Front

Where does the main source of energy for all life come from?

Back

The main source of energy for all life comes from the sun.

Front

Which gas is removed from the atmosphere during photosynthesis?

Back

Carbon dioxide is removed from the atmosphere during photosynthesis.

Front

What role do chlorophyll a and b play in photosynthesis?

Back

Chlorophyll a and b absorb light energy, primarily in the blue and red wavelengths, to facilitate photosynthesis.

Front

What is the byproduct of photosynthesis?

Back

Oxygen is the byproduct of photosynthesis.

Front

What is the significance of glucose produced in photosynthesis?

Back

Glucose serves as an energy source for plants and is used in cellular respiration.

Front

What are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the light-dependent reactions and the light-independent reactions (Calvin cycle).
