Answer
Leaves
Reason — Stomata are present on the surface of leaves to facilitate exchange of gases between the leaf and the atmosphere.
Roots absorb water and minerals from the soil. They do not have stomata because gas exchange is not their primary function. Some green stems may have stomata, but they are far fewer compared to leaves. In woody stems, gas exchange happens through lenticels instead. Petals are mainly for attracting pollinators and generally lack stomata or have very few that are not functionally significant.
