WebHow plants respond to hormones. The five major groups of plant hormones — auxins, cytokinins, gibberellins, ethylene, and abscisic — acid are distinguished by their chemical structures and the response they evoke within the plant (see Table 4.1). For any cell to respond to a hormone it must be competent to perceive the chemical. WebCytokinins help in increasing the cell division by maintaining the protein production that is important for mitosis. The term Mitosis refers to a non-sexual division of cells that usually occurs in all the living things by …
WebCytokinins. These are produced in the regions where cell division occurs; mostly in the roots and shoots. They help in the production of new leaves, lateral shoot growth, chloroplasts in leaves etc. They help in overcoming apical dominance and delay ageing of leaves. Also Read: Cytokinins. Functions of Cytokinins. Break bud and seed dormancy. WebCytokinins were discovered as kinetin. Kinetin does not occur naturally but scientists later discovered several natural (example – zeatin) and synthetic cytokinins. Natural cytokinins exist in root apices and developing shoot buds – areas where rapid cell division takes place. Effects. Help in the formation of new leaves and chloroplast.
WebCytokinins. The effect of cytokinins was first reported when it was found that adding the liquid endosperm of coconuts to developing plant embryos in culture stimulated their growth. The stimulating growth factor was found to be cytokinin, a hormone that promotes cytokinesis (cell division). Almost 200 naturally occurring or synthetic ...
WebFeb 1, 2001 · Most bacteria can only form the tRNA-bound cytokinins, but there are examples of plant-associated bacteria, both pathogenic and beneficial, that actively synthesize cytokinins to interact with their host. Similar to plants, bacteria produce diverse cytokinin metabolites, employing corresponding metabolic pathways. china sticksWebApr 04,2024 - Cytokinins help to produce all excepta)new leacesb)chloroplast in leacesc)lareral shoot growth and adventitious shoot formationd)rooting on cut stemCorrect answer is option 'D'. ...
