Epidermis covers the upper and lower surfaces of the leaf. Epidermis mediates exchanges between the plant and its environment, limiting water loss, controlling gas exchange by opening and closing stomata.

Answer 2

Answer:

Hii,

Explanation:

$\huge\boxed{\mathcal\red{Answer:-}}$

UPPER EPIDERMIS:- It protects against water loss, regulate gas exchange, secretes metabolic compounds, and (especially in roots) absorbs water and mineral nutrients.

LOWER EPIDERMIS:- A protective layer of cells. The lower epidermis produces a waxy cuticle too in some plant species. The lower epidermis contains pores called stomata that allow carbon dioxide and oxygen to move in and out of the plant respectively.
