Hormonal Plants

Hormonal Plants 

Auxins

Auxins control the growth of plants. These auxins possess the ability to allow the stems of plants to elongate and to be able to enable other parts of the plant to grow. Auxins also have the ability to control a plant's reaction to light and other stimuli. 

Abscisic Acid

This acid performs the opposite actions of the auxins in the plant. This acid slows the growth of plants in order to preserve the plants when there is not enough water around. This acid also has the ability to put the seeds of the plant into a dormant state when it is necessary. 

Ethylene

Ethylene is a gas produced by plants under a positive feedback loop. This ethylene controls the ripening of the fruits on a plant.
