Auxin causes a plant to grow larger by: Group of answer choices a. Causing an asymmetric increase in the length of the stem or root. b. Stimulating the apical meristem to produce new cells. c. Causing an increase in the speed of cell divisions and maturation. d. Stimulating the acidification of cell walls causing cell enlargment

Respuesta :

Answer: Option A

Explanation:

Auxin is a well known plant hormone which helps in the elongation of the cell and also helps in the inhibition of the growth of lateral buds.

Auxins are produced in root tips, stem and buds. They move to the darker side of the plant which causes the cell to grow larger in the darker side as compared to that of the lighter side.

It also helps in the apical dominance of the plant. Example: Indole acetic acid.
