(i) Tissue culture process produces new seedlings from plant parts like roots, stems, leaves, flowers, fruits, pollinators etc.
(ii) In this process the plant body cells are multiplied by producing flower and fruit seedlings with maternal quality.
(iii) Plants that do not produce seeds are propagated by producing seedlings from their organs.
(iv) Plants which are on the verge of extinction are being saved from extinction by producing new seedlings from any part of them.
(v) In interspecies hybridization complete hybrid plants are produced by embryo culture and embryo development.
(vi) New plants can be formed by separating the embryonic tissue from the pollinated ovules. At present research is going on with plants like Cucumis melo, Aegle marmelos, Liffa cylindrica etc.
