Because the stoma must open to exchange oxygen and carbon dioxide, and water vapor is lost in the process.
Evaporation of water through the plant's leaves is called transpiration.
The two structures in plant leaves that help prevent the loss of water are the cuticle, a waxy layer on the outer surface of the leaf, and stomata, small openings on the underside of the leaf that can open and close to regulate water loss.

Transpiration is water loss from plants.
Water moves from roots to leaves through a process called transpiration. Transpiration is the loss of water from a plant's leaves through tiny pores called stomata. This loss of water creates a negative pressure in the leaves, which pulls more water up through the plant's vascular system from the roots.

The loss of water vapor from a plant is called transpiration. It is the process by which water is evaporated from the plant's leaves into the atmosphere.
The loss of water from the leaves of plants is known as transpiration. It is a crucial process in which water is taken up by roots and released through leaf stomata as vapor. This helps in maintaining the plant's internal water balance.

A snake plant closes up its leaves to conserve water and reduce moisture loss during dry conditions.
Transpiration is the loss of water by a plant through it's stems or leaves.
Plants lose leaves to reduce water loss through transpiration during dry or cold periods. This helps conserve water and energy for the plant's survival. Additionally, shedding leaves can increase the plant's tolerance to freezing temperatures.

Plant stems and leaves have a waxy cuticle to prevent water loss through evaporation and protect against environmental stress. Since roots are in direct contact with the soil, they do not face the same risk of water loss and therefore do not require a cuticle layer.
When a plant is placed in a plastic bag, the enclosed environment creates a high humidity level within the bag. This high humidity reduces the rate of transpiration, which is the process of water loss from the plant through its leaves. As a result, the plant conserves water and slows down the overall rate of water loss.
