Schizosaccharomyces pombe is species of Yeast under the Fungi kingdom and it is also named 'fission yeast'. It is commonly used model organism, due to it having many cellular processes similar to Homo sapiens, and its relavtive ease to genetically manipulate
The cells themselves have a rod shape structure and divide via 'fission'. This is where 'division occurs when a septum, or cell plate, forms midway along the rod.'.
Growth during fission initially occurs at one end of the yeast cell, however when NETO (New end take-off) occurs (if the cell is 9.5 μm long and has been in the cell cycle for 0.34 of a cell cycle) growth can occur at both ends of the cell.
