ANATOMY

Detailed explanation-1: -As with photosynthesis, plants get oxygen from the air through the stomata. Respiration takes place in the mitochondria of the cell in the presence of oxygen, which is called “aerobic respiration". In plants, there are two types of respiration: dark respiration and photo respiration.

Detailed explanation-2: -Plants take in oxygen and give out carbon dioxide during respiration all the time.

Detailed explanation-3: -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-4: -The respiration in plants differs from that of animals. In other words, in plants, each part can independently take in oxygen from air, utilize it to obtain energy, and give out carbon dioxide.

Detailed explanation-5: -Tulsi. An Indian household is usually incomplete without the presence of a sacred Tulsi plant. Every day, Tulsi gives out oxygen for 20 out of the 24 hours day. It absorbs toxic pollutants from the air such as carbon dioxide, carbon monoxide and sulphur dioxide.
