                                                                             FEATURES

A) SHOOT BUD                                 i) Originated from the many cells, usually superficial

B) SOMATIC EMBRYO                        ii) Polarity is defined as bipolar; both shoot and root poles present
                                                        iii) Vascular strands connected with those present in callus/explant
                                                       iv) Easily separated from the callus/explant
                                                        v) There is no vascular connection with callus/explant
