When this behavior depends upon a stimulus, it is classified as either a taxis, a kinesis, or a tropism.
This process is induced in  Magnetospirillum  bacteria upon introduction of a magnetic field, and cAMP  (c-a-m-p)  induces it in the genus  Dictyostelium  by forming a slug. The rate of this cellular process is measured in an assay where the experimenter literally scratches a tissue with a pipette. Actin polymerizes at the lamellipodium, or leading edge, during this process. It's not mitosis, but in most eukaryotes, this process is accomplished by an organelle homologous to a (*)  centriole composed of a 9-plus-2 axoneme linked to a basal body. When this behavior depends upon a stimulus, it is classified as either a taxis, a kinesis, or a tropism. Amoebas accomplish this process with pseudopodia. For 10 points, name this basic cellular process facilitated by flagella and cilia.
This process is induced in  Magnetospirillum  bacteria upon introduction of a magnetic field, and
cellular  motion  [or  locomotion ; or  motility ; or  movement ; or other word forms; or cellular migration ; or cellular  aggregation ; accept  taxis  or  chemotaxis  or  magnetotaxis  until "taxis" is read]
