The best understood bacterial cytoskeleton are composed primarily of what?

Answer & explanation:

The cytoskeleton is a net-like structure of cells composed of three types of protein filaments, these are:

The microtubules, responsible for both the shape and the movement (action of eyelashes and flagella) of the cells;

microfilaments, that contribute to the movement, the functions of the plasma membrane, the fight against infections and skin healing processes.

In addition, there are also the intermediate filaments, which are thicker than microfilaments and thinner than microtubules and have the function of holding cell organelles in place.

The cytoskeleton is composed mainly of proteins such as actin, which forms the microfilaments and tubulin, which is part of the microtubule structure.

organisms that are both used in toothpaste as well as cause malaria are protista and monera.
