Bacteria MCQs

Hello students, our next topic for MCQs is ‘Bacteria’. Bacteria are the small microscopic organisms. The structure of bacteria consists of following parts like Cytoplasm, Pilius, Cell wall, Ribosome, Bacterium Flagellum, Capsule and DNA. The morphological types of bacteria are also seen which we are going to discuss through MCQs. The reproduction in bacteria takes place by both ways i. e. Sexual reproduction and asexual reproduction. The sexual reproduction occurs through Pilius and asexual reproduction is through Binary fission.
