these is due to complex body of multicellular organisms because multicellular organisms has many cell to perform different functions by different cell as per the body design for control and coordinate all the body parts.

Answer 2

In them, cells are organised into specialised groups/tissues, organs and/or systems, each of which occupy specific locations in the body. In such an organised condition, cell-by-cell division would be impossible. Hence multicellular organisms need complex methods of reproduction.
