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.
Auxins are the plant hormones produces at the tip of a shoot and root. Auxins are present at the tip of tendrils. When tendrils are attached around any support their growth is slowed down as auxins are sensitive to touch. This make them move to the other side of the tip to get support this makes theRead more
Auxins are the plant hormones produces at the tip of a shoot and root. Auxins are present
at the tip of tendrils. When tendrils are attached around any support their growth is
slowed down as auxins are sensitive to touch. This make them move to the other side of
the tip to get support this makes the other side grow faster than the side of tendril in
contact with the support and the tendril bends towards the support.
Auxins and Gibberlins are the hormone responsible for the growth of plant. Auxins are responsible for the cell elongation in shoot and also regulates growth. Gibberlin is responsible for stem elongation and germination.

Movement of leaves of the sensitive plant 1. It does not depend on the direction of stimulus applied. 2. Touch is the stimulus. 3. Caused by the sudden loss of water from the swellings at the base of leaves. 4. Occurs very fast Movement of a shoot towards light 1. Depends on the direction of stimulRead more

1. It does not depend on the direction of stimulus applied.
2. Touch is the stimulus.
3. Caused by the sudden loss of water from the
swellings at the base of leaves.
4. Occurs very fast
Movement of a shoot towards light
1. Depends on the direction of stimulus applied.
2. Light is the stimulus.
3. Caused by the unequal growth on the two sides of the shoot.
Plant hormones are the organic substances produces at certain sites of the plant and are translocated to other parts based on the requirement. Plant hormones help to coordinate growth, development and responses to the environment. Ex: Auxin’s Gibberlin’s, cytokines, abscisic acid and ethylene.

How do auxins promote the growth of a tendril around a support?
Auxins are the plant hormones produces at the tip of a shoot and root. Auxins are present at the tip of tendrils. When tendrils are attached around any support their growth is slowed down as auxins are sensitive to touch. This make them move to the other side of the tip to get support this makes theRead more

Give an example of a plant hormone that promotes growth.
Auxins and Gibberlins are the hormone responsible for the growth of plant. Auxins are responsible for the cell elongation in shoot and also regulates growth. Gibberlin is responsible for stem elongation and germination.
