Detailed explanation-1: -Plants get carbon dioxide from the air through their leaves. The carbon dioxide diffuses through small holes in the underside of the leaf called stomata. (One of these holes is called a stoma. The plural is stomata.
Detailed explanation-2: -Carbon dioxide and oxygen cannot pass through the cuticle, but move in and out of leaves through openings called stomata (stoma = “hole"). Guard cells control the opening and closing of stomata. When stomata are open to allow gases to cross the leaf surface, the plant loses water vapor to the atmosphere.
Detailed explanation-3: -Final answer: The part of the plant that takes in carbon dioxide from the air for photosynthesis is the stomata.
Detailed explanation-4: -Stomata are the small pores present on the leaves of the plant. Carbon dioxide enters the plants through these openings.
