Question

Name the plant hormone that prevents wilting in plants

Answer 1

Hi friend !

The answer is Cytokinins
========================================
The plants do not have a nervous system and sense organs like ear ,nose ,mouth,etc like the animals , but they can still sense things.
The plants coordinate their behavior against environmental changes by using hormones.
The functions of control and coordination in plants is performed by certain chemical substances.These chemical substances are called plant hormones or phytohormones.
There are four major types of plant hormones [phytohormones] . which are involved in the control and coordination  in plants.These are :
1)Auxins
2)Gibberellins
3)Cutokinins
4)Abcisic acid

1)Auxins are the plant hormones which promote cell enlargement and cell differentiation. Auxins also promote fruit growth. Auxin hormone is responsible for phototropic and geotropic responses of plants.

2) Gibberellins are plant hormones which promote cell enlargement and cell differentiation in the presence of auxins. Gibberellins help in breaking the dormancy in seeds and buds. They  also promote fruit growth. Gibberellins stimulates elongation of shoots of various plants

3) Cytokinins are plant hormones which promote cell division in plants.They also help in breaking the dormancy in seeds and buds. The delay the ageing of leaves.Cytokinins promote opening of stomata .

4)Abscisic acid (ABA) is a  plant hormone which functions mainly as a growth inhibitor. Abscisic acid promotes the dormancy in seeds and buds [ this is the opposite of breaking the dormancy]. It also promotes closing of stomata. Abscisic acid promotes falling of leaves.
