Question

Identify the force responsible to coalesce liquid drops to form single one

​

Answer 1

Answer:

Positive pressure is the force in the xylem which exudates drops of liquids through the stoma to the outside and also requires hydathodes which help in the process of guttation (exudation of water droplets mostly from the leaves margins). So, the correct is 'Positive pressure'

Answer 2

Answer:

Negative hydrostatic pressure develops at the time of water loss, it occurs when the water is lost through transpiration and creates tension in the cell.

Transpiration is the process in which water is lost through the upper or aerial plant parts in the form of water. 

Imbibition is the swelling of cells that occurs due to the absorption of water. 

Positive pressure is the force in the xylem which exudates drops of liquids through the stoma to the outside and also requires hydathodes which help in the process of guttation (exudation of water droplets mostly from the leaves margins). 

So, the correct option is 'Positive pressure'.
