(N/A) $\Rightarrow$ In unicellular organisms,mitosis is often referred to as binary fission or simple cell division,where the cell directly divides into two daughter cells.
$\Rightarrow$ In multicellular organisms,mitosis is a complex,indirect process involving the replication of $DNA$ and the formation of distinct chromosomes.
$\Rightarrow$ In unicellular organisms,the process is relatively simple and primarily serves the purpose of reproduction.
$\Rightarrow$ In multicellular organisms,the process involves highly regulated phases: $Prophase$,$Metaphase$,$Anaphase$,and $Telophase$,followed by cytokinesis,which is essential for growth,tissue repair,and development.
