Question

In the experiment to demonstrate root pressure, where did the cut was made on the plant?

• A. At the tip
• B. Transition zone
• C. A few centimeters above the soil
• D. A few centimeters below the soil

Answer 1

Answer: (C)

A few centimeters above the soil

Root pressure is the transverse osmotic pressure within the cell of root that causes the rise of sap through the stem of the plant. So, to demonstrate root pressure the cut made is on the shoot just a few centimetres above from the ground.

So, the correct answer is 'A few centimetres above the soil'.
