Interphase: Cells may appear inactive during this stage, but they are quite the opposite. This is the longest period of the complete cell cycle during which DNA replicates, the centrioles divide, and proteins are actively produced. For a complete description of the events during Interphase, read about the Cell Cycle. A neat lab sheet introduces cell biologists to the general structure of both animal and plant cells. They draw and label what they observe under high power. After examining the cells of an onion root tip, budding biologists analyze numbers of cells in each different phase of mitosis.

First add a few drops of water or solution on the microscope slide to avoid dryness and wilting. Take a small piece of onion and using tweezers, peel off the membrane from the underside (the rough side). Place the membrane flat on the surface of the slide. Add a drop of Iodine solution to the onion skin. For organisms to grow and reproduce, cells must divide. Mitosis and meiosis are both processes of cell division, but their outcomes are very different.
