The role of a cytoskeleton in a living cell is to supply structure to the cell, give the cell the ability to move and ensure proper cell division during cellular reproduction. The cytoskeleton contains three types of filaments within the cytoplasm, including intermediate filaments, microfilaments and microtubules.Continue Reading
Unlike human skeletons, cytoskeletons are extremely dynamic, meaning that their filament systems can lengthen or shorten rapidly. The dynamic nature of a cytoskeleton is required for cells to have the ability to change their shape and to ensure successful cell division or migration.
The filament systems of a cytoskeleton share a vital feature: they are made of proteins that can assemble themselves into a filamentous network.
The essential role the cytoskeleton plays in cell proliferation has led to cytoskeleton-inhibiting anti-cancer drugs.Learn more about Cells
According to a 2006 study of sexually transmitted diseases, the bacterium Mycoplasma genitalium is the smallest living cell as of 2014. It measures only 200 to 300 nanometers, according to Wikipedia.Full Answer >
Eukaryotic cells are advanced cells that have, at minimum, a cellular membrane surrounding cytoplasm, a cytoskeleton and membrane-covered organelles. More advanced eukaryotic cells also contain a nucleus that protects genetic material.Full Answer >
The cytoskeleton is the three-dimensional scaffolding present in eukaryotic cells. The structure functions similarly to both the muscles and skeleton of animals in that it provides support and causes movement. Its structure is made from three primary types of fibers, known as microfilaments, microtubules and intermediate filaments.Full Answer >
According to science writer Clare Smith for SeattlePi, the cell membrane is kept from collapsing by its phospholipid bilayer, maintenance of the correct temperature, a cytoskeleton and cell junctions. These are necessary because the cell membrane is one of the most crucial components of a cell.Full Answer >
