Which hormone helps cytokinin in the process of plant cell division and differentiation?
The cross-talk between cytokinin and auxin in the shoot and root meristem is highlighted in Figure 2. In the root meristem, auxin induces the meristematic cell division, whereas cytokinin promotes the cell to switch from the meristematic to differentiated state through inhibiting auxin signaling.Feb 28, 2011
Which plant hormone responsible for cell division and cell differentiation?
Cytokinins promote cell division, cell growth and differentiation along with auxin. Ethylene is responsible for fruit ripening. Abscisic acid helps the plant to sustain in adverse conditions. Gibberellins enable the plants to grow taller.
Which hormone is used in cell division in plants?
Auxin controls stem cell specification and cell division in the meristem.Jan 28, 2014
Which control cell division and cell differentiation is?
Epigenetic Control of Cell Division and Cell Differentiation in the Root Apex. Epigenetics is defined as heritable changes in gene expression and genome integrity that are accompanied by no alteration in DNA sequence.
Which is the main plant hormone that induces cell division?
Final answer: Cytokinin is the phytohormone that is involved in cell division. Q. Name a plant hormone which promotes cell division.
Which hormone helps in plant cytokinesis?
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.
Which hormone controls cytokinesis?
Cytokinins play an important role in cytokinesis process. Cytokinins are naturally synthesised in the plants where rapid cell division occurs e.g. root apices, shoot buds, young fruits, etc.May 20, 2022
Is cytokinesis a plant hormone?
Cytokinins are a class of plant-specific hormones that play a central role during the cell cycle and influence numerous developmental programs. Because of the lack of biosynthetic and signaling mutants, the regulatory roles of cytokinins are not well understood.
What is cytokinin hormone?
Cytokinins are plant-specific chemical messengers (hormones) that play a central role in the regulation of the plant cell cycle and numerous developmental processes. Cytokinins were discovered by F Skoog, C Miller, and co-workers during the 1950s as factors that promote cell division (cytokinesis).
Which hormone helps in Karyokinesis?
So, the correct answer is 'Cytokinin'.
Which plant hormone is responsible for cell division in plant?
Auxin promotes cell division and meristem maintenance and also plays an important role in the establishment of cellular patterning.
