Given below are two statements: One is labelled as Assertion (A) and the other is labelled as Reason (R):
Assertion (A): Positive xylem pressure causes exudation of sap through hydathodes, a process called guttation.
Reasons (R): Guttation is noticed when transpiration is suppressed and relative humidity is high.
