Epidermal Cells

Cells making up the epidermis, the outermost layer of the skin, serving as the body’s protective barrier against environmental stressors, pathogens, and water loss.

Transpiration

The loss of water vapor from the aerial surfaces of a plant (i.e., leaves and stems).

Humidity

The amount of water vapor present in the air, often described as relative humidity.

Wind

The movement of air from areas of high pressure to low pressure, often responsible for changes in weather.
