A list of the cell fibers from largest to smallest would read:
1. microtubules – is a microscopic tubular structure that is present in numbers in the cytoplasm of cells. These are usually aggregated to form complex structures.
<span>2. intermediate filaments – are cytoskeletal components that is usually found in the cells of vertebrate species and </span>other organisms like plants, fungi, unicellular organisms.
3. <span>Microfilaments – are filamentous structures that can be found in the cytoplasm of eukaryotic cells and it will form part of the </span>cytoskeletons<span>. They are composed primarily of polymers of actin. But in cells, they usually interact with other proteins.</span>
The molecule will enter the cell using a channel protein.
