Question

Answer to question number 3 please!!!

Answer 1

Complex organisms are not simply random collection of cells, where specialised cells are organised as tissues, and tissues are organised as organs, which then have to be placed at definite positions in the body. In such a situation, cell by cell division would not be practical. Multicellular organisms, therefore, need to use more complex ways of reproduction.

Answer 2

hi frnd!!! hope this will help you.....

• Complex organisms do not have regenerative cells.

• Complex organism has different organ system. All the organs are interconnected to each other.

• And so regenaration cannot be followed by complex organisms.
