Amoebas are unicellular organisms, while human beings are multi-cellular and the most intelligent of organisms. However, both are classified as eukaryotes. How will you justify this reasoning?
(a)Though unicellular, amoebas have all the necessary cell organelles and a well-defined nucleus, therefore fulfilling the characteristics of eukaryotes.
(b) Though unicellular, amoebas have a nucleoid and no cell organelles, therefore fulfilling the characteristics of eukaryotes.
(c) Though unicellular, amoebas have a nucleolus but not a nucleus and all the cell organelles except mitochondria, therefore fulfilling the characteristics of eukaryotes.
