Hormone connected with cell division, is
A
IAA
B
NAA
C
Cytokinin/zeatin
D
Gibberellic acid
Answer
Cytokinin/zeatin
Explanation
Solution
Cytokinin has a very specific effect on cell division (cytokinesis), hence the name cytokinin. They contain kinetin and related compound generally called as kinins chemically, cytokinins are degradation product of adenine, ATP, NAD and NADP. Cytokinins are essential for cytokinesis though chromosome doubling can occur in their absence. Cytokinins bring about division even in permanent cells.
