The magnitude of root pressure ranges from:

Options

  1. A2-5 ~atm
  2. B1-5 atm
  3. C0.1-0.2 atm
  4. D4-6 arm

Correct answer

B. 1-5 atm

Step-by-step solution

The term root pressure was coined by Stephen Hales (1727). The evidences that support the existence of this phenomenon are bleeding and guttation. The magnitude of root pressure is 1-2 ~atm and very rarely 5 atm.
