The part of a plant that collects water (and nutrients) from the soil (ground) is called the root ([Plural] - roots). The outside surface of the root is the epidermis. Surface (epidermal)cells on the epidermis absorb water and nutrients from the surrounding environment and produce outgrowths called root hairs that greatly increase the cell's absorptive surface, allowing it to absorb more water. The process by which water is absorbed into the epidermal cells from the soil is known as osmosis. For this reason, water that is saline (contains salt) is more difficult for most plant species to absorb.
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.
root cells
Turgid cell
A plant's epidermis is primarily used for protective purposes, which it does by acting as a barrier to invaders (such as fungi). Another important function is in the prevention of water loss (for this reason, epidermal cells are packed tightly together). This water loss is further prevented by the waxy cuticle layer many plants have, located above the epidermal cells.
root hairs
The cells of the epidermis (skin) absorb water and swell up.

Coastal plants have plenty of water to absorb and transpire therefore their epidermis does not require water conservation; on the other hand non coastal plants have to conserve water hence their epidermis is thick.

Dermis is covered by epidermis. There are cells, which are tightly packed. Epidermis is covered with waxy coating to prevent the water loss. The surface area of the leaves is very large. That is needed to absorb more and more light. This large surface area will lose lot of water. That is risky. So the adaptation. Tried to tell you. Though I am not a botanist.
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.

water
its the other way around plant cells do absorb water while animals do. plants absorb water for photosynthesis
It helps prevent water loss
They absorb it from carbon dioxide and the sun and water.
