Question

What are plant harmones? Function each of the plant harmone

Answer 1

HEYA MATE,

• PLANT HORMONES ARE ALSO CALLED PHYTOHORMONES.
• THEY ARE HORMONES IN PLANTS THAT HELP IN CONTROL AND COORDINATION OF VARIOUS PLANT PARTS.
• THERE ARE MAINLY 5 MAIN HORMONES: AUXIN, CYTOKININ, GEBARALLIC ACID, ABSSSACCIC ACID, ETHYLENE.
• AUXIN HELPS IN CONTROLLING GROWTH OF PLANT PARTS MAINLY MERISTEMS.
• CYTOKININ ALSO PROMOTES CELL DIVISION BUT RAPIDLY, IN FRUITS AND SEEDS MAINLY.
• GEBARALLIC ACID HELPS IN PROMOYING INTER-NODAL ELONGATION.
• ABCCASSIC ACID HELPS IN INHIBITING GROWTH OR STOP GROWTH TO REDUCE OVER-GROWTH.
• ETHYLENE HELPS IN RIPENING OF FRUITS.

CHEERS MATE!!!!!!!       MARK AS THE BRAINLIEST!!!!!!!!!!!!!

Answer 2

PLANT HORMONE :

=> these are the chemical substance that are naturally produced in plant and are capable of regulating the important process of the plant. different plant hormone help to co-ordinate , growth development , and response to environment

PLANT HORMONE AND THEIR FUNCTIONS :

1. AUXIN : it is the hormone which is usually synthesized in a young tip of the root and shoot.

when the light is coming from one side of the shoot of a plant diffuses towards the shaded region of side of the plant plant which stimulate the cell to grow longer resulting in the bend of shoot towards light .

2. CYTOKININS :

1. in mature plants , cytokinins are produced in the root tips and transported to shoot .

2. cytokinin promotes the cell division and also help in Breaking dormancy of seed and buds and regulated to phloem transport .

3. it promotes the opening stomata

3. ABSCISIC ACID :

1. its effect includes wilting of leaves .

2. it causes dormancy of seeds , tuber and buds

3. it promotes the closing of stomata and is responsible for loss of protein and chlorophyll RNA

4. GIBBERLINS :

=>these are the hormones that helps in growth of stem and flowers highest concentration of gibberlins occurs in fruit and seeds. they help in seed to germinate

5. ETHYLENE :

1. essential for ripening of fruit

2. help to promote cell division

3. promotes the transverse growth

4. gaseous hormone that acts throughout the life of the plant and is known as ripening hormone
