Answer 2

Hey there !

# Phyto or plant hormones are the hormones which help the plants for their growth.

# There are mainly 5 types of plant hormones :-

1) Auxin Hormones

2) Cytokinin Hormones

3) Gibberellin Hormones

4) ethylene Hormones

5) abscisic Hormones

# Functions :-

* Functions of Auxin : Cell enlargement, apical dominance, prevention from bending; promote xylem differentiation, healing of wounds of plants.

* Function of Cytokinin : promote cell division, apical dominance, delay in senescenes ( aging ), phloem transport, accumulation of salts in cells, production of female flowers .

* Functions of Gibberellin : promote increase in fruit size, inter-nodal elongation, seed germination

* Functions of Abscisic Acid : abscission of leaves, reduce transpiration, inhibit cambium activity, bud dormancy in seed during winter, seed development and maturation, induce flowering .

* Functions of Ethylene : inhibit stem elongation; promote fruit ripening, increase girth of stem, speed of senescence, abscission of leaves.
