Oral apparatus regeneration and reorganization in Stentor. When the original oral apparatus (green) is removed, an oral primordium (red) forms at the locus of stripe contrast. This primordium, consisting of thousands of basal bodies, organizes into a new oral apparatus as it migrates to the anterior end of the cell. The same process can also occur spontaneously, creating a reorganization in which the old oral apparatus is replaced by a new, usually larger one.
