Answer 1

Loss of water as droplets from hydathodes is called guttation.

Explanation:

Guttation is the process by which liquid water is forced out as droplets from the margins or uninjured tips of leaves through specialised water pores called hydathodes. This phenomenon occurs when high root pressure builds up in the plant, combined with low transpiration rates typically seen during humid nights or early mornings. In contrast, transpiration and evaporation release water as invisible vapour, while bleeding is the loss of fluid from cut or injured surfaces.
