Question

Force responsible for exudation of liquid drops from the margin of the leaves is
A. Negative hydrostatic
B. Transpiration pull
C. Imbibition
D. Positive pressure

Answer 1

Powers, including gravity, are continuously following up on plants and cause them to be moving. Plants can be moving simply like we are moving. Plants move when they develop or react to their current circumstance. The water inside a plant cell applies a power, called turgor pressure and many other forces are responsible for different processes.

Complete answer:
Force responsible for the exudation of liquid drops from the margin of the leaves is defined as positive pressure.

Positive pressure- Positive weight inside cells is contained by the cell, delivering turgor pressure in a plant. Turgor pressure guarantees that a plant can keep up its shape. A plant's leaves wither when the turgor pressure diminishes and restore when the plant has been watered. It is seen in the process of guttation.

Transpirational pull- The happening occurring through leaves causes negative weight or pressure in xylem sap which is communicated to the root. This is called transpirational pull theory which is liable for the development of the water section upward.

Imbibition- Sachs accepted that water is assimilated through the cell divider materials and transferred upwards. Along these lines, the hypothesis expresses that climb of sap happens through the wall, yet it is obvious that water is trans-situated through the lumen of the vessels.

Negative hydrostatic- Negative hydrostatic weight creates at the hour of water deficiency, it happens when the water is lost through happening and makes pressure in the cell.

Hence, the correct answer is option (D).

Note: Guttation is the exudation of drops on the tips of leaves of some vascular plants (possessing xylem and phloem), for example, grasses, and various organisms. Guttation isn't to be mistaken for dew, which gathers from the air onto the plant surface. Guttation by and large occurs during the evening.
