Cytokines biology definition
WebThe cytokinin zeatin is named after the genus of corn, Zea. Cytokinins ( CK) are a class of plant hormones that promote cell division, or cytokinesis, in plant roots and shoots. They are involved primarily in cell growth and differentiation, but also affect apical dominance, axillary bud growth, and leaf senescence. WebCytokinesis is the phase when cell division actually occurs through the physical separation of the cytoplasmic contents into two genetically identical daughter cells. Cytokinesis completes the mitotic phase of the cell cycle, and which often happens concurrently with mitosis. Although the steps of mitosis are similar in most eukaryotes, the ...
