Question

What is the function of upper and lower epidermal cells

Answer 1

heyyy mate............

Upper and lower epidermis are the two outermost layers of the leaf.

The upper epidermis contains a thick cuticle in order to prevent the water loss and provides an extra layer between the outside and inside of the leaf.

The lower epidermis contains more stomata than the upper epidermis, facilitating the gas exchange and also helps to  prevent water loss.
