transpiration
Yes, transpiration is beneficial for plants because it helps to cool them down, transport nutrients and water, and maintain their shape and structure.
Increasing surface area via capillary action
The stomata are small openings in the leaf that control the exchange of gases, such as oxygen and carbon dioxide. They open to allow for gas exchange during photosynthesis and close to prevent water loss through transpiration.
A cell is a complete structure, it controls itself.

Transpiration is the process that controls the amount of water stored in the leaves of a plant. It involves the loss of water vapor through tiny pores on the surface of leaves called stomata. Transpiration helps regulate the amount of water taken up by the roots and transported throughout the plant.
