How does moisture affect the evaporation of plants?

Ambient humidity can vary depending on air temperature, atmospheric pressure and many other factors. This affects the evaporation of water from plant leaves. When the air humidity is low, the plant begins to lose water. Everything is conditioned by physical laws. The plant tries to conserve water, so there is a layer of wax on the leaves, they have a specific shape and size. When the air humidity is increased, the leaves do not lose water, and evaporation occurs normally.
