Transpiration, the loss of water in the form of water vapor, occurs through stomata. Stomata open to allow water vapor to escape from the plant, contributing to the movement of water through the plant and the maintenance of water balance.
How does transpiration occur in plants, and what role do stomata play in this process?

Transpiration in plants is the process of water loss through small pores called stomata, primarily found on leaves. As water vapor escapes through these openings, it creates a negative pressure gradient, facilitating the movement of water from roots to leaves via the xylem. Stomata regulate transpiration by opening and closing to balance water loss with gas exchange needs.
