For all study island cheaters out there, I feel your pain. The answer is prevent water loss.
A major function of the epidermis is to prevent water loss. The outermost layer of the epidermis, called the stratum corneum, acts as a barrier to prevent excessive water loss from the body. This barrier function helps to maintain hydration and protect the deeper layers of the skin.
The epidermis is a single-layered group of cells that covers plants' leaves, flowers, roots and stems. It forms a boundary between the plant and the external environment. The epidermis serves several functions, it protects against water loss, regulates gas exchange, secretes metabolic compounds, and (especially in roots) absorbs water and mineral nutrients.

Cuticle! ♡
A cell is dependent on nutrients and other molecules diffusing into the cell. This process works most efficiently when the surface area to volume ratio is higher. If there were a cell the size of a person, the necessary nutrients would not diffuse fast enough for cell function.

The main function of the epidermis is to protect. It protects the individual from bacteria, maintains temperature, and acts as wrap to contain all of an individual's parts.
plant roots posses root hairs which anchor the plant in soil and their major function is to absorb water and nutrients from soil. if there will be waxy cuticle on there epidermis it will be hard for roots to absorb nutrients and water from soil hence plant without water and nutrients will die.
The Upper Epidermis is used to prevent water loss
The main job of the epidermis is to prevent microbial pathogens from entering the body. The epidermis is a barrier for the body.

The function of root hairs is to absorb water and nutrients from the soil. If the root hairs have a cuticle covering, it will prevent the free absorption of water and nutrients from the soil.
