On the underside of leaves, there are pores-like proteins called Stomata (Singular-Stoma). THese pores open, close, or partially open depending on the climate. The wider open the pores are, the more transpiration occurs. When the plant wants to conserve water, the proteins close or partially close to limit the amount of evaporation.

The loss of water from plants back into the atmosphere?
The "loss" of water vapor from stoma on the underside of the leaf is called transpiration. Transpiration also provides assistance in the uptake of water by plants, as water is lost through the leaves a low pressure is created within the leaf, assisting with the "suction action" of water being drawn up the vessels in the plant stem (simplified explanation
How does a leaf obtain its water?
A leaf obtains water through the process of transpiration, where water is absorbed by the roots from the soil and transported to the leaves through the xylem vessels. Once in the leaves, water is used in various metabolic processes and is also lost through small openings called stomata during transpiration.
What kind of vapor can be lost from a leaf besides gases?
In addition to gases, water vapor can also be lost from a leaf through a process called transpiration. This is where water evaporates from the leaf surface into the surrounding air. This loss of water vapor plays a crucial role in maintaining the plant's hydration and nutrient transport.
Is the same amount of water is being lost from the surface?
Of and as?
In Pokemon LeafGreen what is in lost cave?
How to get to lost cave in leaf green??
What protects a plant from water loss?
A layer of the leaf called the cuticle cuts down on water lost by evaporation. Also, the guard cells around the stomata which can close to prevent water loss.
How does a leaf prevent from dehydrating?
A leaf prevents dehydration through a process called transpiration. Specialized cells called stomata regulate how much water is released from the leaf, and a waxy cuticle on the leaf's surface helps reduce water loss. The plant also transports water from the roots to the leaves to replace what is lost through transpiration.
Through which structure of a leaf is most mater vapour lost into the atmosphere?
The stoma on the underside of the leaf
What effect moving the fan nearer to the cut shoot have on the rate of transpiration?
When water is lost from the leaves of a plant (transpiration), it forms a thin layer of water vapour on the leaf's surface. Windy conditions destroy this thin boundary, thus, maintaining the water potential gradient across the leaf and shortening the path for the water to reach the atmosphere.
How transpiration is responsible for the movement of water in the xylem?
Transpiration is the loss of water from the plant through evaporation at the leaf surface. It is the main driver of water movement in the xylem. Transpiration is caused by the evaporation of water at the leaf, or atmosphere interface; it creates negative pressure (tension) equivalent to -2 MPa at the leaf surface. However, this value varies greatly depending on the vapor pressure deficit, which can be insignificant at high relative humidity (RH) and substantial at low RH. Water from the roots is pulled up by this tension. At night, when stomata close and transpiration stops, the water is held in the stem and leaf by the cohesion of water molecules to each other as well as the adhesion of water to the cell walls of the xylem vessels and tracheids. This is called the cohesion-tension theory of sap ascent.
How does the transpiration affects the distribution of stomata in a leaf?
Transpiration in a leaf causes water to be lost through the stomata, leading to a decrease in internal water pressure. To compensate for this loss, stomata are typically distributed more on the lower surface of a leaf where there is less direct sunlight and wind exposure, helping to reduce excessive water loss and maintain the plant's hydration levels.
What is Waxy layer of the leaf?
The waxy layer of the leaf, known as the cuticle, is a waterproof barrier that covers the outer surface of the leaf. It helps prevent excessive water loss from the leaf through evaporation and protects the leaf from damage by external factors such as UV radiation and pathogens. The cuticle also serves to reduce water droplet formation on the leaf surface, helping to prevent fungal growth.
