Photosynthesis and Respiration GATE

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 role of chlorophyll in photosynthesis?

Back

Chlorophyll is a green 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

What is the equation for photosynthesis?

Back

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

Front

What is respiration in plants?

Back

Respiration is the process by which plants convert glucose and oxygen into energy, carbon dioxide, and water.

Front

How do plants obtain carbon dioxide for photosynthesis?

Back

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

Front

What is the significance of oxygen produced during photosynthesis?

Back

Oxygen produced during photosynthesis is essential for the survival of most living organisms, as it is used in cellular respiration.

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 produces carbon dioxide.

Front

What is the role of water in photosynthesis?

Back

Water is a raw material in photosynthesis; it provides hydrogen and is split to release oxygen during the process.

Front

What is the function of the thylakoid membranes in chloroplasts?

Back

Thylakoid membranes contain chlorophyll and are the site of the light-dependent reactions of photosynthesis.
