Question

Where does transpiration cohesion pull theory works?

• A. Active absorption
• B. Inactive absorption
• C. Active and Inactive absorption
• D. None of these

Answer 1

The correct option is B Inactive absorption

Transpiration cohesion pull theory works during inactive absorption. During inactive absorption, there is no active involvement of the root cells during the process of transpiration. According to passive absorption theory, the forces responsible for absorption of water originate not in the cells of roots but in the cells of transpiring shoots.
