Question

why do we say that the single celled organisms are immortal?

or there is no natural death in single celled organisms?

Answer 1

Hii..

Single celled organisms doesn't have natural death because growth and reproduction refers to same activity in such unicellular organisms..

In order to reproduce they need to divide by mitosis and thereby dividing into two new unicellular organisms..

In this way it continues to carry on hence there is no natural death for unicellular organisms.

Hope it helps..!!

Answer 2

hey dear here's the answer
"A single celled organism keeps on dividing into two by asexual reproduction. so, at the end of their life cycle they simply divide and do not die naturally...... so, until and unless these forces come into play the cell keeps on dividing and we can say that there is no natural death to the organism.
