The cytoskeleton is made up of protein threads. It is responsible for holding the cell in place, maintaining cellular shape and supporting the cell membrane. Plant and animal cells contain three basic types of protein thread. Actin filaments, or microfilaments, are the thinnest type, while intermediate filaments are thicker and stronger. Microtubules are larger still with a hollow center and are essential for mechanical support.
Summary. Exoskeletons are the hard coatings on the outside of some animals, mostly arthropods. It is nonliving, made of chitin and calcium carbonate. Exoskeletons support the animal's body and protect the creature from predators, water, and drying out.t also protects the animal's soft, inner organs and muscles from injury. That's probably why so many movie heroes and heroines don metal exoskeletons when going into battle. Compared to those of us with endoskeletons, it seems like an excellent survival strategy.
