how does control and coordination take place in plants
Answers
Control and coordination takes place in plants by the hormonal system .
Answer:
Control and coordination take place in plants through the use of hormones. These hormones responsible for control and coordination are called phytohormones. Phytohormones are of four types:
Auxin: Released on the tip of the roots and stems. Its function is to make cell growth and cell differentiation. Also, it promotes growth in fruits.
Gibberellin: Its function is the same as the auxin. However, it also helps in breaking the dormancy in seeds and buds.
Cytokinin: it helps in cell division. It delays the aging of leaves. Also, it helps in opening the stomata.
Abscisic acid: It promotes dormancy. It closes the stomata. It promotes the wilting and falling of leaves.
Auxin, Gibberellin and Cytokinin are called growth promoters in the plants. Abscisic acid is called a plant inhibitor.
