Question

Root pressure theory was accepted for translocation in the

• A. Xerophytic plants.
• B. Short plants.
• C. Tall plants.
• D. Both B and C.

Answer 1

The correct option is B Short plants.

The short plants are considered to have low gravitational force. The water column is maintained due to the transpiration pull. The root pressure theory explains that the pressure or suction created by transpiration is enough to produce root pressure which helps to absorb more water. It was the assumption that there is high hydrostatic pressure in the soil which allows absorption by these plants. Due to transpiration, there is high root pressure which allows absorption of the water.

Thus, the correct answer is option B.
