Detailed explanation-1: -Plants get carbon dioxide from the air through their leaves. The carbon dioxide diffuses through small holes in the underside of the leaf called stomata. (One of these holes is called a stoma. The plural is stomata.
Detailed explanation-2: -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-3: -Final answer: Plants take carbon dioxide from the atmosphere mainly through their stomata.
Detailed explanation-4: -Answer: Solution 11: (ii)Which part of the plant takes in carbon dioxide from the air for photosynthesis Stomata.
