Introducing the Cell Cycle. The eukaryotic cell cycle is divided into four phases, designated G 1, S, G 2, and M respectively (see the figure to the right). Collectively, the G 1, S, and G 2 phases are referred to as interphase (designated I in the figure), and take up approximately 90% of the cell's lifespan.ntroducing the Cell Cycle.

Eukaryotic Cell Structure and Function A cell is defined as eukaryotic if it has a membrane-bound nucleus. Any organism composed of eukaryotic cells is also considered a eukaryotic organism. Case in point: you. Oh, and all other people, too. Biologists do not know of any organism that is composed of both eukaryotic and prokaryotic cells.
