Protocorms obtained by seed germination have many close similarities with those produced from isolated shoot tips; the term protocorm like-bodies has introduced when cloning orchids by meristem culture. Laibach demonstrated the practical application of this technique by isolating and growing the embryos of interspecific cross. Tissue culture definition is - the process or technique of making body tissue grow in a culture medium outside the organism; also : a culture of tissue (such as epithelium).
