A . It occurs through specialized pores called hyathodes.
B . It occurs in herbaceous plants when root pressure is low and transpiration is high.
C . It only occurs during day time.
D . It occurs in plants growing under conditions of low soil moisture and high humidity.
Answer: Option A : A Guttation refers to the exudation of water droplets from the margins and tips of leaves. Guttation water is exuded from group of leaf cells through specialized openings or pores called hyathodes. It occurs in some angiosperms like garden nasturtium (Tropacolum) colocasia, tomato, etc., and is most noticeable where transpiration is suppressed and relative humidity is high such as during the night. It also takes place the early morning, when soil moisture, root pressure and rate of water absorption is higher.
