Detailed explanation-1: -Carbon dioxide enters the leaves through tiny pores present on the surface of the leaves called stomata. Note: Photosynthesis occurs during the day time.

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: -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-4: -Carbon dioxide from the air enters the leaf through the stomata.

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.
