Cells that are capable of being transformed are called "competent" Generated by Koofers.com. “Transformation” may also be used to describe the insertion of new genetic material into nonbacterial cells, including animal and plant cells; however, because “transformation” has a special meaning in relation to animal cells, indicating progression to a cancerous state, the term should be avoided for animal cells when describing introduction of exogenous genetic material. In microbial genetics, the transfer of genetic material contained in "naked" DNA fragments from a donor cell to a competent recipient cell.
