Yes, the stomata, which are pores in the lower epidermis of the leaf and are surrounded by 2 guard cells, open in the day to let in CO2 for photosynthesis but they also release H2O as water vapour and they close at night to reduce water loss.
Stoma (pl. stomates, stomata) - Tiny openings in the epidermis that allow water, oxygen, and carbon dioxide to pass into and out of a plant.
These openings are called stomata.

The small openings of the epidermis of a herbaceous stem are called stomates. These tiny opening are found on the underside of stems and through them gases and water vapors are exchanged.
Plants breathe through small openings in their leaves called stromates, which open and close with water availability.
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.
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 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 leaves have openings called stomata.
The upper epidermis is responsible for preventing water loss by evaporation. It does this by having a waxy cuticle on the top of the leaf. The lower epidermis has stomata, which allow gases to enter and leave the leaf as a result of photosynthesis and respiration.

the small openings on the underside of a leaf allow water to come in and replenish the leaf :D
The small openings of the epidermis of a herbaceous stem are called stomates. These tiny opening are found on the underside of stems and through them gases and water vapors are exchanged.
They are called stomata, tiny holes that regulate the intake/output of gas, such as carbon dioxide and oxygen.
No in fact they have multiple openings called pores, which allow water and nutrients to flow in and out of the sponge
