In which among the following, cell division itself is a mode of reproduction?
Escherichia, Euglena and Amoeba
In unicellular organisms like protists (eg., Amoeba and Euglena) and monerans (eg., Escherichia) reproduction occurs through binary fission which is a type of cell division. Penicillium undergoes both sexual and asexual reproduction. Asexual reproduction begins with the formation of asexual spores. Hydra reproduces by fragmentation. Bryophyllum, ginger, potato and Nostoc all reproduce by vegetative methods.
