Question

Plzzz tell me about the types of ""Plant Hormones"" and their function in detail nd very easy ( effective ) language

Answer 1

hey mate here is your answer....

1.) Auxin

This hormone is present in the seed embryo, young leaves, and apical buds' meristem.

Functions of Auxins
Stimulation of cell elongation, cell division in cambium, differentiation of phloem and xylem, root initiation on stem cuttings, lateral root development in tissue culture.

2.)Cytokinin

They are synthesized in roots and then transported to other parts of the plant.

Functions of Cytokinins
Stimulation of cell division, growth of lateral buds, and apical dominance.




3.)Ethylene

Ethylene is present in the tissues of ripening fruits, nodes of stems, senescent leaves, and flowers.

Functions of Ethylene
Leads to release of dormancy state.


4.)Abscisic Acid

Abscisic acid is found mostly near leaves, stems, and unripe fruit.

Functions of Abscisic Acid
Stimulation of closing of stomata.



5.)Gibberellin

Gibberellins are present in the meristems of apical buds and roots, young leaves, and embryo.

Functions of Gibberellins
Stimulates stem elongation

WHAT ARE PLANT HORMONES?
============================
In plants coordination mainly happens by certain chemicals which are known as plant hormones are they are termed as phytohormones.

WHAT ARE THE TYPES OF HORMONES?
===================================
There are 4 types of HORMONES. They are as follows :-

1) Auxins :- Auxins are plant hormones which are produced at the shoot tips in the presence of sunlight. This hormone promotes cell elongation and cell division. This results in cell growth of the stem m

2) Gibberellins:- Gibberellins are plant hormones which helps in the growth of the plant. It results in the increasing of fruits and flowers. It also helps to stimulate cell elongation and cause plants to grow This hormone also have a role in other plant processes such as germination.

3) Cytokinins:- Cytokinins help cell division. It delays aging in plants i. e. the plants don't die quickly, they remain young for longer period of time.

4) Abscisic Acid :- This hormone inhibits growth. So, it does not allow the plant to grow further. It reverses the effect of auxins and Gibberellins. Because of the presence of this hormone, the leaves of the plant wilt, dry and get decayed. This hormone involves in the closing of stomata, bud seed dormancy and is known to inhibit other hormonal actions.
