Question

What is hydropism describe an experiment to demonstrate hydrotropism

Answer 1

The movement of the plant in the direction of stimulus is called tropism.

AIM: To demonstrate hydrotropism in plants.

PROCEDURE :

i. Plant a seedling in a vessel containing soil.

ii. Adjacent to the seedling put a porous pot containing water.

iii. Leave the set up for few days.

OBSERVATION :

iv. On examining the roots of seedlings it is observed that the roots bend towards the source of water and do not grow straight.

RESULT :

It confirms that plant shows hydrotropism as the roots bend towards the porous pot of water. As hydrotropism is a plant growth response in which the direction of growth is determined by a stimulus of gradient in water concentration.
