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 (a 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 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 to 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 factors affect the rate of photosynthesis?

Back

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

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

How do plants obtain carbon dioxide for photosynthesis?

Back

Plants obtain carbon dioxide from the atmosphere through small openings in their leaves called stomata.

Front

What is the role of water in photosynthesis?

Back

Water is a raw material in photosynthesis; it is split into hydrogen and oxygen, with hydrogen being used to form glucose.

Front

What is the light-dependent reaction in photosynthesis?

Back

The light-dependent reactions occur in the thylakoid membranes of chloroplasts, where light energy is converted into chemical energy (ATP and NADPH) and oxygen is released.
