Question

How can you show that plants absorb water through their roots?

Answer 1

Answer:

We can get this experiment by taking the plant with the roots in a test tube and then filling the test tube with water upto the stem of the plan. The plant must be near to a plantlet and not some big plant.

Then it can be observed after a certain time the water level will continue to decrease and finally will be depleted from the test tube and this proves that the water is absorbed through the roots of the plant.

Answer 2

Plants absorb water through their roots, and this can be explained by a simple experiment with tuberoses.  

Explanation:  

• Tuberoses can be used to prove this simple experiment. Two tuberose sticks can be taken and immersed in a glass tumbler full of colored water.
• It can be seen after some hours that the white tuberose has turned slightly colored and the amount of water in the tumbler has reduced.
• This proves that the water has entered the tuberoses and colored it. This experiment can be used to prove that plants absorb water through their roots.
