Question

Name 5 plant hormones and state their functions.

Answer 1

$\huge\bf\blue{Hey\:Mate!!!}$

Plant Hormones :

$\bf\red{1.Auxin}$

-Stimulates growth by call elongation

-produces apical dominance

-indicates development of dwarf shoots

-induces parthenocarpy

$\bf\red{2.Gibberlins}$

-induce stem elongation

-suppresses 'genetic dwrafism'

-promotes flowering in long day plants under short day conditions

-much more potent than auxin in inducing parthenocarpy

$\bf\red{3.Cytokinin}$

-chemical substance responsible for cell division

-promotes cell division and related DNA and RNA synthesis

-causes cell enlargement in some plants

$\bf\red{4.Ethylene}$

-gaseous hormone

-its fruit ripening hormone

-produces leaf abscission

-induces flowering in pineapple

$\bf\red{5.Abscissic\: acid}$

-inhibits physiological activities of plants

-accelerates abscission of leaves

-inhibits germination of seeds

Answer 2

Answer:

Explanation:

The five plant hormone are:

1 auxins- it is present in root and shoots.it helps in cell differentials,cell enlargement, support photo and Geo tropism

2 gibberlins- support cell enlargement, cell differentials, it breaks the seed dormancy ( the condition where seed is inactive)

3 cytokinins- indicates cell division,it delays the aging of leaves,opening of stomata,breaks seed and bud dormancy

4 absicis acid- acts as growth inhibitor,shedding of leaves,closing of stomata, promote seed and bud dormancy.....
