Plant Hormones

Ethylene

Ethylene is a plant hormone that encourages ripening. It is created from the plants endoplasmic reticulum and is created relative to the rate at which it is excreted from a plant. It's function is to create create sugar out of starch and acid in order to make fruits taste more delicious. Farmers use ethylene to quickly ripen their fruits

Auxin

Auxin is a plant hormone that is produced from a plant embryo. It is essential in stimulating plant elongation, stimulatin cell division in the cambium, as well as being essential in differentiation in phloem and xylem. This is used by farmers to have plants grow a lot faster than they usually do and to increase the size of their plants. Auxin is created in the tip of a plant and is then transferred to the dark side of the plant and cell divides. This creates cell elongation in the direction of light.



Abscisic Acid

Abscisic Acid is a plant hormone that saves a plant from dying when under stress. It inhibits plant growth so that when for example, it is without water for a long period of time, will not die but will lay dormant until better conditions arise.
