Answer 1

Answer: (A)

Liquid form containing dissolved minerals.

The process by which plants loose water in liquid form is called guttation. Guttation is the exudation of drops of xylem sap on the tips or edges of leaves of some vascular plants, such as grasses. This process can usually be witnessed in plants in early morning and at night, mostly in herbaceous plants growing in high humidity conditions and high moisture of soil. Guttation water contain many dissolved minerals. It occurs only in some plants like grasses, colocasia, tomato, etc. The water that is lost in this process is not pure but contains minerals, organic acids, sugars and even enzymes. So, the correct answer is option A.
