Hello students, our next topic for the MCQ is ‘PROKAYROTIC CELLS’. The prokaryotic organisms do not possess a nucleus. The E. coli is an example of prokaryotic cell. The prokaryotic cells have capsule and it is a thick layer made up of polysaccharides. It protects prokaryotic cell from drying out and helps in the attachment to surfaces.
The following MCQ will help you more to understand this topic.
