Question

assertion - guttation takes place through hydothodes reason - each stomatum is sourrounded by two kidney shaped guard cells the dicots​

Answer 1

Answer:

The process of exudation of liquid drops from the edges of leaves is called guttation. Usually it occurs through stomata-like pores called hydathodes. It is this process by which fully turgid plants remove extra water. The cause of guttation is mainly root pressure(when the root pressure is high and rate of transpiration is low, guttation takes place). Hydathodes are stomata like pores generally present at the tips or margins of leaves of those plants that grow in most shady places (e.g) Tropaeolum).

So, the correct answer is 'When the root pressure is high and the rate of transpiration is low'.
