Another term, cell culture is used for in vitro culture of single or relatively small groups of plant cells, e.g., suspension cultures. But in general, the term tissue culture is applied to both callus and suspension cultures, and cell culture is often used for callus culture as well.
When organised structures like root tips, shoot tips, embryos, etc. are cultured in vitro to obtain their development as organised structures, it is called organ cultures. In this book, the term tissue culture is used in its broad sense to denote aseptic culture of plant cells, tissues, and organs.
