Photosynthesis GATE

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 primary pigment involved in photosynthesis?

Back

Chlorophyll is the primary pigment that absorbs sunlight during photosynthesis.

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose and oxygen.

Front

What role does carbon dioxide play in photosynthesis?

Back

Carbon dioxide is one of the raw materials used in photosynthesis to produce glucose.

Front

What is the significance of water in photosynthesis?

Back

Water is essential for photosynthesis as it provides electrons and protons, and it is split to release 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

How does light intensity affect photosynthesis?

Back

Increased light intensity generally increases the rate of photosynthesis, up to a certain point.

Front

What is the role of sunlight in photosynthesis?

Back

Sunlight provides the energy needed for the photosynthesis process to convert carbon dioxide and water into glucose.

Front

What is glucose used for in plants?

Back

Glucose is used by plants as a source of energy and as a building block for growth.
