Question

Guttation is the process of elimination of water from plants through

• A. Stomata
• B. Hydathodes
• C. Lenticels
• D. Wounds

Answer 1

The correct option is B Hydathodes

Guttation is the process of loss of impure water (a dilute solution of different organic and inorganic substances) from the plant (mostly from margins of leaves). It occurs when transpiration rate is very low as compared to the rate of water absorption. Due to this root pressure is developed and water is pushed out through specialized pores at vein endings called hydathodes. Each hydathode is made up of a group of loosely arranged achlorophyllous or colorless and parenchymatous cells called epithem.

So, the correct answer is option B.
