Q. 9 :- How are the modes for reproduction different in unicellular and multicellular organisms?
Unicellular organisms always reproduce by asexual methods; like binary fission, budding, multiple fission, etc. Multicellular organisms, on the other hand, use both asexual and sexual methods for reproduction. While simple organisms usually follow the asexual methods of reproduction; most of the multicellular organisms follow sexual methods of reproduction.
