The process responsible for facilitating loss of water in liquid form from the tip of grass blades at night and in early morning is

Options

  1. ARoot pressure
  2. BImbibition
  3. CPlasmolysis
  4. DTranspiration

Correct answer

A. Root pressure

Step-by-step solution

Loss of water from the uninjured part or margin of leaves of the plant in the form of water droplets is called guttation. Exuded liquid of guttation along with water contains some organic and inorganic (dissolved) substances. It means it is not pure water. Normally, guttation process is found in herbaceous plants and occurs during mid-night or early morning. The process of guttation take place due to root pressure, develop in cortex cells of the root.
