Based on the material used, how will you classify the culture technology?

Explanation

Based on the explants some other plant tissue culture types are
(a) Organ culture
(b) Meristem culture
(c)  Protoplast culture 
(d) Cell culture
(a) Organ culture:
The culture of embryos, anthers, ovaries, roots, shoots or other organs of plants on culture media.
(b) Meristem Culture :
The culture of any plant meristematic tissue on culture media.
(c) Protoplast Culture:
Protoplasts are cells without a cell wall, but bounded by a cell membrane or plasma membrane. Using protoplasts, it is possible to regenerate whole plants from single cells and also develop somatic hybrids.
(d) Cell Suspension Culture :
The growing of cells including the culture of single cells or small aggregates of cells in vitro in liquid medium is known as cell suspension culture. The cell suspension is prepared by transferring a portion of callus to the liquid medium and agitated using rotary shaker instrument. The cells are separated from the callus tissue and used for cell suspension culture.
