why do we say there is no natural death in single celled organisms?
There is no natural death in single celled organisms because they clone themselves into two new organisms when they reproduce. There doesn't seem to be anything about their cells that wears out after they have reproduced themselves a given number of times.
Hope this helps,
Ok. let me explain the answer in more easy way.
Death do occur in unicellular organismsbut according to thr research we have not determied single celled organisms undergoing undergoing natural death but there are probably others in which natural death may occur.
We say that single celled organisms do not undergo natural death because these organisms also have a cell which begins the development nd gradually looses the power of cell multiplication and thus, have to be renewed by the rejuvenating process.
Hope now this is clear,
