Question

From active hydathodes, the water comes out by

• A. Osmotic pressure
• B. Secreted by force developed within cells
• C. Root pressure
• D. None of the above

Answer 1

The correct option is C Root pressure

From hydathodes water is lost in liquid form through a process called as guttation. The force responsible for guttation is root pressure. Guttation occurs when loss of water through transpiration is less and excess water is absorbed by plant roots.

So, the correct answer is 'Root pressure'
