The process responsible for facilitating loss of water in liquid form ...
Root pressure (positive pressure)  can be responsible for pushing up water to small heights in the stem. “It also observable at night and early morning when evaporation is low, and excess water collects in the form of droplets around special openings of veins near the tip of grass blades, and leaves of many herbaceous parts.
 

Such water loss in its liquid phase is known as guttation. Imbibition is the adsorption leading to absorption of water by hydrophillic substances. Plasmolysis is the shrinking of the cell membrane and cytoplasm when a cell is undergoing exosmosis. The loss of water in the form of water vapor from the aerial parts of the plant is called transpiration.

Root Pressure as a Process for Water Loss in Grass

Introduction:
Grass blades lose water in liquid form during the night and early morning. The process responsible for this phenomenon is the subject of the question.

Explanation:
The process responsible for facilitating loss of water in liquid form from the tip of grass blades at night and early morning is root pressure. This process involves the movement of water from the roots of a plant to the leaves due to pressure generated by the root system.

When the plant is well watered, root pressure builds up until it becomes strong enough to force water out of the leaves through small openings called stomata. This process is more active at night when the transpiration rate is low and the relative humidity is high.

As a result, grass blades release water in liquid form during the night and early morning. This process is important for the survival of the plant because it helps to prevent excess water loss during the day when the transpiration rate is high.

Conclusion:
In conclusion, root pressure is the process responsible for facilitating loss of water in liquid form from the tip of grass blades at night and early morning. This process helps to prevent excess water loss during the day and is important for the survival of the plant.
