These cells will not be dividing
|

These cells divide very slowly

|
These cells divide continuously
|

|
None of the above

Detailed explanation-1: -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-2: -So, the correct option is ‘Neither mitogens nor energy-rich compounds are present. ‘
Detailed explanation-3: -In the G0 phase, there is no cell division. It is the resting phase of the cell cycle. Cells in the G0 phase exit the cell cycle and re-enter after receiving signals.
Detailed explanation-4: -So, the correct option is ‘Mitosis occurs after G0 phase’.
Detailed explanation-5: -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.
