Explanation:

The main  function of the plasma membrane is to protect the cell from its surroundings. Made of a phospholipid bilayer with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules it also regulates the movement of substances in and out of cells. Plasma membranes must be very flexible in order to allow certain cells, such as red blood cells and white blood cells, to change shape as they pass through narrow capillaries. Membrane receptors provide extracellular attachment sites for effectors like hormones and growth factors, which then trigger intracellular responses. Some viruses, such as Human Immunodeficiency Virus (HIV), can intercept  these receptors to get into the cells, causing infections.

What is a function of a bacterium's capsule?
nevsk [136]

The purpose of a bacterium's capsule is protection.

<h3>What use does the capsule of a bacteria serve?</h3>

White blood cells may eat and kill pathogens, but capsules could stop that from happening (phagocytosis). Although the precise mechanism for avoiding phagocytosis is unknown, it may occur because the presence of capsules makes the surface elements of bacteria more slippery, preventing the bacterium from being absorbed by phagocytic cells.

Capsules comprised of bacterial defenses and the host. The main function of the capsules of pathogenic bacteria is to prevent opsonophagocytosis or in the case of Gram-negative bacteria, complement-mediated lysis by shielding the bacterial surface from interactions with the host immune system.
