Answer:
A recombinant plasmid gets inside a bacterial cell by transformation.
Step-by-step explanation:
A recombinant plasmid can be described as a plasmid which carries a foreign DNA.
In genetics, transformation can be described as a process by which a cell takes genetic material from its environment. The cell tends to take the genetic material directly through its cell membrane.
The phenomenon of transformation is very common in bacterial cells to occur. So, transformation is the best method by which a recombinant plasmid can be introduced in a bacterial cell.
