Text Solution

Verified by Experts

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.
