The chromosome of an untransformed Escherichia coli strain encodes the enzymes necessary for the bacterium to grow on a medium that contains either glucose or galactose as a carbon source. This same chromosome carries a mutation in the fliC gene. fliC is necessary for the production of flagella used in cell motility. The mutated gene prevents the cell from producing functional flagella. As a result, cells with this mutation are non-motile.
This strain is transformed with a plasmid that carries a wild-type fliC gene and bla, a gene that encodes the enzyme beta-lactamase, which confers resistance to the antibiotic ampicillin. Following the transformation reaction, these cells are grown on two different media: a medium that contains glucose only and a medium that contains galactose and the antibiotic ampicillin.
Which of the following statements regarding the growth of the cells on these media is TRUE?
