What uses stomata as its route into the leaf?
A
carbon dioxide
B
ions
C
sunlight
D
water
Explanation: 

Detailed explanation-1: -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-2: -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-3: -Stoma (Plural: stomata) is a tiny opening present on the surface of leaves. It has a pore regulated by guard cells and gaseous exchange takes place through it. Carbon dioxide enters the leaf and water vapour and oxygen leave the leaf through this.

Detailed explanation-4: -Stomata are the small pores present on the leaves of the plant. Carbon dioxide enters the plants through these openings.

Detailed explanation-5: -Most plants use a pore-like structure called stomata (singular: stoma) on the undersides of leaves to absorb carbon dioxide from the air. The carbon dioxide is used to build sugars, which can be used by the plant as energy or for incorporation into the plants’ fibrous cell walls.
