Question

In which among the following, cell division itself is a mode of reproduction?

• A. Amoeba, Hydra and Penicillium
• B. Escherichia, Euglena and Amoeba
• C. Hydra, Nostoc and Euglena
• D. Bryophyllum, Ginger and Potato

Answer 1

The correct option is B

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.
