Question

With the help of an experiment, prove that roots are more positively hydrotropic than geotropic.

Answer 1

Following things are required for this experiment:

Seeds of bean, a deep tray, sand, a porous flower pot

Procedure:

• The tray should be big enough to accommodate the porous pot.
• Fill the tray with sand and insert some seeds in it.
• Make a pit in the sand and insert the porous pot in it.
• Fill the porous pot with water.
• Leave the set up for about a week.

Observation:

After a week when seeds are taken out, it is observed that roots grow in the direction of the porous pot. This shows hydrotropic movement in roots
