Question

Why do multicellular organisms use complex way of reproduction​

Answer 1

Answer:

Multicellular organisms cannot reproduce by cell because they are not simple random collection of cells. In them, specialised cells are organized  as tissues and tissues are organised into organs, which then have to be kept at different positions in the body. Cell-by-cell division would be impractical. Multicellular organisms, therefore, require to use more complex ways of reproduction. Moreover, simple multicellular organisms possess special type of tissues which have the potential to grow into a new organism but complex multicellular organisms have no such specialised cells.
