Question

A list of the cell fibers from largest to smallest would read: 1. microtubules, intermediate filaments, microfilaments

Answer 1

Cell fibers can be listed from largest to smallest as microtubules, intermediate filaments, and microfilaments. Microtubules handle organelle movement and cell division, while intermediate filaments provide structural support, and microfilaments enable cell shape and movement.

Step-by-step explanation:

Understanding Cell Fibers: Microtubules, Intermediate Filaments, and Microfilaments

Cell fibers play a critical role in maintaining the structure and function of cells. If we list these fibers from largest to smallest, we get: microtubules, intermediate filaments, and microfilaments. Microtubules are hollow tubes essential for guiding organelle movement and chromosome separation during cell division. Intermediate filaments, which include proteins like keratin, provide tensile strength and support cellular structure. Microfilaments are the thinnest fibers and they contribute to cell movement and shape maintenance.

Answer 2

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.

2. intermediate filaments – are cytoskeletal components that is usually found in the cells of vertebrate species and other organisms like plants, fungi, unicellular organisms.

3. Microfilaments – are filamentous structures that can be found in the cytoplasm of eukaryotic cells and it will form part of the cytoskeletons. They are composed primarily of polymers of actin. But in cells, they usually interact with other proteins.
