DENDROLOGY

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: -Plants take up the water that they need from the soil through their roots. 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.

Detailed explanation-3: -They need two key gases: oxygen is used in aerobic respiration, where food molecules are broken down to release energy for growth. This process releases carbon dioxide as a waste product. carbon dioxide is used in photosynthesis, where the sun’s energy is harnessed to make food.

Detailed explanation-4: -Carbon dioxide and water are used as raw materials during photosynthesis to manufacture complex carbohydrates such as sugars and in most of the cases, oxygen is released as a waste product. Hence, the process of photosynthesis involves the intake of carbon dioxide and the release of oxygen.
