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 is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a pigment found in the chloroplasts of plants that absorbs sunlight, which is essential for the process of photosynthesis.

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose and oxygen.

Front

Where does photosynthesis primarily occur in plants?

Back

Photosynthesis primarily occurs in the leaves of plants, specifically in the chloroplasts.

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 most living organisms, and it forms the base of the food chain.

Front

What is the difference between photosynthesis and respiration?

Back

Photosynthesis converts light energy into chemical energy (glucose) and releases oxygen, while respiration breaks down glucose to release energy and consumes oxygen.

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.

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 for the process.

Front

What is the light-dependent reaction in photosynthesis?

Back

The light-dependent reactions occur in the thylakoid membranes of chloroplasts, where sunlight is converted into chemical energy in the form of ATP and NADPH.
