All living organisms are born from single cells..
They further get divided with the help if nucleus. ..as an easy exampke we can observe amoeba...it starts from sigke body,then a slight differce takes place ie the nucleus starts divideding and a constriction appears betwwn the it..atlast ig fully divide s itself...
So we can assume that thux process also occurs in cells of an organism!!
hope thus helped
If so mark jt as brainliest answer. ..
