Botany - Cell Cycle and Cell Division Question with Solution | TestHub

Cell cycle is divided into two phases - Interphase and Mitosis (M) phase. The interphase is further divide into 3 phases - Gap/G _ophase, $\left({\mathrm{G}}_1\right)$phase, Synthesis (S) phase and$\mathrm{ }\left({\mathrm{G}}_2\right)$phase. Certain types of cells in the body divide occasionally when there is a need. These type of cells do not proceed further in the cell cycle and exit the${\mathrm{G}}_1$phase to enter into a stage of inactivity known as the quiescent stage or${\mathrm{G}}_{\mathrm{o}}$phase. In this stage the cells remain metabolically active but do not proliferate unless and until there is need. Multinucleated muscle cells, heart muscle cells and neuronswhich doesn't undergo cytokinesis and are considered to be in the G₀stage, which will never enter the G1 phase.
