Question

Which of the following functions does a capsule NOT perform for a prokaryote? A. Hiding antigens to protect from your immune system. B. Protect against desiccation. C. Protection from viruses. D. Protection from organelles.

Answer 1

The correct answer is option D, that is, protection from organelles.

The capsule is regarded as a virulence factor as it increases the tendency of a prokaryote, like bacteria to cause disease. The capsule can protect the cells from engulfment by the eukaryotic cells, like macrophages, thus, it protects against the immune system. Capsules also comprise water that safeguards the cell against desiccation.

They also help to protect against viruses and the majority of hydrophobic toxic elements, like detergents. Capsules also assist cells in sticking with the surfaces.
