What gas is TAKEN IN during photosynthesis?
A
argon
B
nitrogen
C
oxygen
D
carbon dioxide
Explanation: 

Detailed explanation-1: -During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.

Detailed explanation-2: -Photosynthesis is the process by which green plants synthesise their own food from carbon dioxide and water in the presence of sunlight and chlorophyll. During this process, oxygen is released as a by-product.

Detailed explanation-3: -Plants use photosynthesis to capture carbon dioxide and then release half of it into the atmosphere through respiration. Plants also release oxygen into the atmosphere through photosynthesis.

Detailed explanation-4: -Carbon dioxide is a gas found in the air; plants can take in this gas through tiny holes in their leaves. Once they have water and carbon dioxide, they can use energy from sunlight to make their food. The leftovers from making the plant food is another gas called oxygen.

Detailed explanation-5: -They take in oxygen and give out carbon dioxide.
