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

(N/A) In unicellular organisms,reproduction occurs by the division of the entire cell. The modes of reproduction in unicellular organisms include fission,budding,etc.
In multicellular organisms,specialized reproductive organs are present. Therefore,they can reproduce by complex reproductive methods such as vegetative propagation,spore formation,and sexual reproduction.
In complex multicellular organisms like humans and higher plants,sexual reproduction is the primary mode of reproduction.
