Explanation:
Detailed explanation-1: -The G0 phase is a form of the resting state, or quiescence, in which cells reside until they receive appropriate signals-for example, from growth factors-stimulating them to re-enter and progress through the cell cycle.
Detailed explanation-2: -Some examples of cells that enter G0 and stay forever are nerve cells and heart cells. This is because once they reach maturity, nerve and heart cells do not divide again, so they stay in the G0 phase.
Detailed explanation-3: -While some cells are constantly dividing, others are quiescent. These cells exit G1 and enter a resting state called G0. In G0, a cell is performing its function without actively preparing to divide.
