Question

Ragu carried out an experiment, he took two conical flasks A and B and filled them with water up to the same level. In flask A, he placed a healthy tuberose plant without root and in flask B he placed a tuberose plant with root in such a way that the bottom of both the plants remains in the water. What is his observation after a couple of hours?

• A. The water level in both the flasks remains unchanged.
• B. The water level in flask A decreased.
• C. The water level in flask B decreased.
• D. The water level in both the flasks changed.

Answer 1

The correct option is C

The water level in flask B decreased.

After the scheduled time is over it will be observed that there is a fall in the water level of the flask B which contained the plant with root showing that the plant has absorbed water. The water level of the flask A remains unchanged. This experiment proves that the plants absorb water.
