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: -The small pores present on leaves help plants take in carbon dioxide and give out oxygen during the process of photosynthesis. These pores are called stomata.

Detailed explanation-3: -Carbon dioxide It moves by diffusion through small holes in the underside of the leaf called stomata. Guard cells control the size of the stomata so that the leaf does not lose too much water in hot, windy or dry conditions. The lower part of the leaf is a spongy layer with loose-fitting cells.

Detailed explanation-4: -Stomata (noun, “STO-mah-tah”, singular “stoma”) These are the small pores in plant stems or leaves that allow carbon dioxide in and oxygen and water vapor out. Each tiny hole is surrounded by a pair of cells called guard cells.

Detailed explanation-5: -Carbon dioxide (a gas) diffuses into the leaf directly through specialized mouth-shaped cells, known as guard cells. The holes made by guard cells are called stomata. Carbon dioxide and water go through a series of chemical reactions in the chloroplasts of plants to produce glucose with oxygen as a byproduct.
