Hydro’ means water. Hydrotropism means growth towards water.
Materials Required: Seed, A big container, Porous water pot, water and Sand.
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.
Auxin is a plant growth hormone. When the tip of the tendril touches a support, then the auxins present on its tip moves to the side of tip which is away from the support, so, due to more auxins in its tendrils away from the support grows faster.

The main differences between the movement of the leaves of a sensitive plant and the movement of a shoot towards light are: Movements of leaves of sensitive plants is a nastic movement which does not depend on the direction of stimulus whereas Movement of a shoot towards light is a tropic movement wRead more
The main differences between the movement of the leaves of a sensitive plant and the movement of a shoot towards light are:
Movements of leaves of sensitive plants is a nastic movement which does not depend on the direction of stimulus whereas Movement of a shoot towards light is a tropic movement which depends on the direction of stimulus.
The chemical substances produced in plants which control growth, development and responses in plants, are called plants plant hormones. For example: Auxins, Gibberellins, Cytokinins and Abscisic acid.

How do auxins promote the growth of a tendril around a support?
Auxin is a plant growth hormone. When the tip of the tendril touches a support, then the auxins present on its tip moves to the side of tip which is away from the support, so, due to more auxins in its tendrils away from the support grows faster.
