Describe the cytoskeleton. Compare the roles of microfilaments, intermediate filaments, and microtubules. Compare and contrast cilia and flagella. Summarize the differences among the components of prokaryotic cells, animal cells, and plant cells.
In 1903, Nikolai Koltsov proposed that the shape of cells is determined by a network of tubules that he termed the ‘cytoskeleton’. The cytoskeleton is a complex, dynamic network of interlinking protein filaments present in the cytoplasm of all cells including bacteria and archaea.
4 kwi 2017 · The cytoskeleton is a network of filaments and tubules that extends throughout a cell, through the cytoplasm, which is all of the material within a cell except for the nucleus. It is found in all cells, though the proteins that it is made of vary between organisms.
The cytoskeleton is a network of different protein fibers that provides many functions: it maintains or changes the shape of the cell; it secures some organelles in specific positions; it enables movement of cytoplasm and vesicles within the cell; and it enables the cell to move in response to stimuli.

The cytoskeleton, the system of protein filaments that permeate the cytoplasmic space of all eukaryotic cells, is primarily responsible for the structural integrity exhibited by a cell and determines its deformation in response to a given stress.
30 paź 2023 · The cytoskeleton performs several important functions in the cell. These include: Maintenance of cell shape and rigidity by providing mechanical support, allowing cells to assume irregular shapes. Provision of support to specialized cell surface projections such as microvilli, cilia and filopodia
