Answer:
Immortal cell line
Explanation:
An immortalised cell line is a population of cells from a multicellular organism which would normally not proliferate indefinitely but, due to mutation, have evaded normal cellular operation and instead can keep undergoing division. The cells can therefore be grown for prolonged periods in vitro
Immortal cell lines are a very important tool for research into the biochemistry and cell biology of multicellular organisms. Immortalised cell lines have also found uses in biotechnology.
Plant cells have a cell wall and cell membrane but animal cell have only a cell membrane.
Muscle cells do not form different types of tissues, the muscle tissue is one of the 4 basic categories of tissues found in humans
