Vedclass · Answer

(C) Cytokinins are a class of plant growth substances (phytohormones) that promote cell division,or cytokinesis,in plant roots and shoots. They were discovered by Miller et al. $(1955)$ and the first natural cytokinin identified was zeatin,isolated from corn kernels. While auxins like $IAA$ and $NAA$ promote cell enlargement and gibberellins promote stem elongation,cytokinins are specifically responsible for stimulating cell division.
