Cytokinin is a plant hormone that helps in cell division. Cytokinin (CK) is a class of phytohormones that stimulates cytokinesis, or cell division, in the roots and shoots of plants. These hormones influence apical dominance, axillary bud growth, and leaf senescence, in addition to being in charge of cell proliferation and differentiation.

Cell Division in Plant Hormone
The hormone necessary for cell division and proliferation is cytokinin. Embryogenesis, the maintenance of roots, and shoot meristems, among other elements of plant growth and development, are all known to be significantly influenced by cytokinin.
The effect of cytokinin on plant growth is greatly influenced by the ratio of auxin to cytokinin, and cytokinin alone does not affect parenchyma cells. They enlarge but do not divide when cultivated with auxin but not cytokinin.
- Auxins are basically a plant hormone class with some characteristics of a morphogen.
- The addition of cytokinin causes the cells to grow and differentiate.
- Auxin and cytokinin are added to the parenchyma cells in equal amounts to create an undifferentiated callus.
Summary:
Which of the following Hormone Promotes Cell Division in Plants? 1. Auxin 2. Abscisic acid 3. Gibberellin 4. Cytokinin
Cytokinin helps in Cell Division and is a type of plant hormone. To produce an undifferentiated callus, parenchyma cells are treated with equal amounts of auxin and cytokinin. More cytokinin is added, which promotes the development of shoot buds, while more auxin promotes the development of roots.
