Question

How would you demonstrate hydrotropism with the help of an example?

Answer 1

Answer:

Expert Answer: 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.

Answer 2

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
