Which part of the plant takes in carbon dioxide from the air for photosynthesis?

Plants function photosynthesis because it brings about the food and energy they need for growth and cellular respiration. For the plants to function photosynthesis, it required light energy, water and carbon dioxide. Light energy can be obtained from the sun, which enters through the chlorophyll present in the leaves. Water is absorbed through the roots and carbon dioxide is absorbed from the atmosphere through pores in the leaves called stomata.
