Answer

  1. Since single-celled organisms reproduce by cell division into two individuals), there is no natural death for them and hence, they are considered immortal.
  2. In multicellular organisms, reproduction occurs in specialised organs involving specialised cells; their body as a whole dies due to ageing and senescence.
