By observing the onion root under the microscope it allows many layers to be looked at through each cell division. Cut all excess from the root tips except for 2mm at the very tip of the root end that was not cut from the plant. Cytokinesis normally occurs next and the single cell develops into two separate cells. G1 and G2 are the two gap phases during which the cell grows, producing proteins and preparing the cells. The first 2 phases of mitosis, interphase and prophase, were observed in the cells of the root tips.

The main harvest continues into August, with the late varieties and spring planted beds being harvested in late August. After interphase, cells are ready for mitosis, which consist of four stages. In a karyotype, the chromosomes are arranged and numbered, based on size from largest to smallest, centromere position and banding pattern due to staining of chromosomes. Plants have a spindle but lack centrioles. Ethano-orcein stain contains ethanoic acid and also requires you to wear goggles when it is dispensed.

Adding a heavy layer of mulch before the ground is frozen can insulate the ground and delay the plants from going dormant naturally. Carefully study the information about the phases associated with mitosis in the Discussion and Review section of your lab manual pages 182- 187. Cell division occurs rapidly in growing root tips of sprouting seeds or bulbs. Alternatives to garlic include onions, hyacinths or seedlings of beans or peas — as long as they are healthy and fast growing. These phases also have certain check points and the whole cell cycle is strictly regulated. There are several protocols available for this work and it is notoriously unreliable — often you will not find many dividing cells at all.
