Question

Which of the following shows guttation ?

• A. Pisum sativum
• B. Ficus bengalensis
• C. Acacia nilotica
• D. Tropaeolum

Answer 1

The correct option is D Tropaeolum

Tropaeolum and strawberry are two prominent example which shows the phenomena of guttation. Tropaeolum majus is a flowering plant in the family Tropaeolaceae, originating in the Andes from Bolivia north to Colombia. The leaf losses water and salts by leaf pores by guttation.

Guttation is the process of loss of impure water from the plant infact, mostly from margins of leaves. It occurs when transpiration rate is very low as compared to rate of water absorption. Due to this root pressure is developed and water is pushed out through specialized pores at the vein endings called hydathodes.

So, the correct answer is option D.
