Micropropagation. Fern being grown in a flask from a tissue culture. The jelly in the bottom of the flask is a sterile soil-substitute containing the nutrients needed by the growing plant. The fern is a clone grown from a tiny fragment or single cell from a "parent" plant in a process called micropropagation. Carefully controlled conditions cause the fragment to develop into an embryo which then produces roots and shoots like a normal seedling. The technique allows mass agricultural production of genetically identical plants and is an effective way of propagating any genes introduced into the parent plant | |
