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 are the main products of photosynthesis?

Back

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

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a green pigment found in plants that absorbs light energy, primarily from the red and blue wavelengths, which is essential for the process of photosynthesis.

Front

What are the raw materials needed for photosynthesis?

Back

The raw materials needed for photosynthesis are carbon dioxide (CO2) and water (H2O).

Front

What is the chemical equation for photosynthesis?

Back

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

Front

How does light intensity affect the rate of photosynthesis?

Back

As light intensity increases, the rate of photosynthesis generally increases until it reaches a saturation point, beyond which it levels off.

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

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen and produces more energy, while anaerobic respiration occurs without oxygen and produces less energy.

Front

What is the role of water in photosynthesis?

Back

Water is a raw material in photosynthesis; it is split into oxygen and hydrogen, providing electrons and protons needed for the formation of glucose.

Front

What factors can limit the rate of photosynthesis?

Back

Factors that can limit the rate of photosynthesis include light intensity, carbon dioxide concentration, temperature, and water availability.
