Question

How are the modes of reproduction different in unicellular and multicellular organism?

Answer 1

The unicellular organisms have only one cell. There is no separate tissue for reproduction. So they can reproduce by the process of fission (binary or multiple) or budding as in yeast.

On the other hand, the multicellular organisms contain various cells and have separate systems for reproduction. So they can reproduce by both sexual and asexual reproduction.
