Question

Why can’t complex, multicellular organisms reproduce by regeneration?

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.

Answer 2

Explanation:

MUTICELLULAR ORGANISM ARE NOT SIMPLY A RANDOM VOLLECTION OF CELLS.

THERE A COMBINATION OF SPECIALISED CELLS DUE TO WHICH SIMPLE RRGENERATION CANT OCCUR IN COMPLEX AND MULTICELLULAR ORGANISM
