Question:

How are the modes for reproduction different in unicellular and multicellular organisms?

Answer:

 In unicellular organisms, asexual reproduction occurs where there is only one parent is involved and no gamete production or parthenogenesis occurs, where one parent cell gets divided into two or multiple daughter cells by binary or multiple fission (eg. Binary fission shown in bacteria, amoeba, planarians and multiple fission shown in plasmodium).

In multicellular organisms, sexual reproduction occurs where two parents are involved to form a zygote or parthenogenesis occurs. All mammals human beings, apes etc. show sexual reproduction process where mother shows viviparity, i.e, gives birth directly to the young ones.
