Plants prepare glucose in the process of:

This question was previously asked in
CDS I 2022 English Previous Year Paper (10-April-2022)
The correct answer is

photosynthesis

The correct answer is Option 2: photosynthesis.

Why this is the correct answer:

Photosynthesis is the process used by plants, algae, and certain bacteria to harness energy from sunlight and turn it into chemical energy.

During this process, plants take in carbon dioxide (\(CO_2\)) from the air and water (\(H_2O\)) from the soil. Using the energy from sunlight (captured by chlorophyll), they convert these ingredients into glucose (sugar), which serves as their food, and release oxygen (\(O_2\)) as a byproduct.

The chemical equation for this process is:

\(6CO_2 + 6H_2O + \text{light energy} \rightarrow C_6H_{12}O_6 + 6O_2\)

Why the other options are incorrect:

Respiration: This is the opposite of photosynthesis. It is the process where plants (and animals) break down glucose to release energy for growth and cellular activities.

Degradation: This refers to the breakdown or decomposition of matter, not the synthesis of food.

Mineral absorption: This is the process by which plant roots take up essential nutrients and minerals from the soil, not how they create energy or glucose.
