Question -
Answer -
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 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.
