Where does carbon dioxide enter a plant?

Question

Where does carbon dioxide enter a plant?

Answer 1

In plants carbondioxide and other gases enter or pass through Stomata - the microscopic pores found on the under side of leaves.

Stomata are present in the sporophyte generation of all land plant groups except liverworts. Dicotyledons usually have more stomata on the lower epidermis than the upper epidermis. Monocotyledons, on the other hand, usually have the same number of stomata on the two epidermes. In plants with floating leaves, stomata may be found only on the upper epidermis; submerged leaves may lack stomata entirely.

Answer 2

stomata

Answer 3

Through little receptors in the leaves.

Answer 4

PLants have special  holes on their leaves called stomata that let gas pass in and out
