PATHOLOGY

Detailed explanation-1: -The G0 phase, also known as the resting phase, is the time when the cell is neither dividing nor preparing to divide. During this time, the cell is performing maintenance and its other functions.

Detailed explanation-2: -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. G0 is a permanent state for some cells, while others may re-start division if they get the right signals.

Detailed explanation-3: -These cells that do not divide further exit the G1 stage to enter an inactive stage called the quiescent stage (G0) of the cell cycle. Cells in this stage remain metabolically active but no longer proliferate unless called on to do so depending on the requirements of the organism.

Detailed explanation-4: -Answer and Explanation: The phase that not all cells enter, but is a phase where cells are not actively dividing is called the G0 or non-dividing phase. No active growth takes place in the cell during this period as the cell is considered to be in a quiescent stage.
