Now the reason it's so long is because interphase actually consists of three individual phases. We have the G One phase, the S phase as well as the G Two phase. Now each one of these phases basically serves its own unique function. So let's actually discuss each one of these individual phases that together make up our interface. So let's begin with the G One phase. So as soon as the cell divides the cell enters the G One phase and the G One phase is known as the growth phase.
