Plant hormones: Auxin, Abscisic Acid, and Ethylene

Plants need hormones just like we do in order to continue homeostasis.

Auxin is a hormone in charge of  mainly growth (cell elongations) but also has other functions such as:

- elongation of cells

- root growth 

- cell division 

- stimulate flower growth

- stimulate fruit growth 

- promote the creation of ethylene

And much much more. Information can be found at: http://www.plant-hormones.info/auxins.htm

The next hormone I will describe is Ethylene. This hormone is gaseous that is mainly in charge of fruit ripening. It also has one of the
simplest structures. 

This hormones functions are: 

- stimulate root growth 

- stimulates fruit to ripen 

- induction of femaleness in dioecious flowers 

- stimulates flower opening 

And more. Information found at: http://www.plant-hormones.info/ethylene.htm

The last hormone is Abscisic Acid. This hormone is mainly in charge of abscission of fruits and bud dormancy. 
This hormones functions are:
- inhibit shoot growth but doesn't affect roots as much
- Induces seed to store protein 
- induce maintenance dormancy 
- stimulates closure of stomata
