Q:

What does the cytoskeleton do in a cell?

A:

The cytoskeleton moves organelles around in a cell, gives the cell shape, helps the cell to move and aids the cell during cell division. The cytoskeleton is made up of protein fibers.

Animal cells do not have cell walls like plant cells do, so they need some kind of structure to keep their shape. This shape formation is accomplished by the cytoskeleton. Many eukaryotic cells contain three types of cytoskeletal structures: microtubules, intermediate filaments and microfilaments.

The cytoskeleton also moves elements around in the cell. During cell division, cytoskeleton components called microtubules pull the chromosomes to opposite ends of the cell so that they can be separated in the daughter cells. Both microtubules and microfilaments move structures called organelles around the cytoplasm. When the cell engulfs something from outside the cell, microtubules and microfilaments transport vesicles formed near the cell membrane toward the center of the cell. Vesicles also play important parts in the packaging plant of the cell, the Golgi bodies, and the transport system of the cell, the endoplasmic reticulum.

Cells move by way of cytoskeleton components. Single-celled organisms such as the paramecium and the Euglena move by way of cilia and flagella. Both cilia and flagella are made of cytoskeletal parts. The amoeba's movement is also governed by cytoskeletal structures.

  • Q:

    What is the function of the cytoskeleton?

    A:

    The cytoskeleton is a network of protein fibers that provide the framework for cellular movement, shape, organelle movement and cell division. These protein fibers make up the microfilaments, intermediate filaments and microtubules.

    What role does the cytoskeleton play in a living cell?

    A:

    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.

  • Q:

    What is cell division?

    A:

    The biological process by which one cell divides into two or more cells is known as cell division. There are two types of cell division: mitosis and meiosis. Mitosis is the most common form of cell division and results in two identical daughter cells, while meiosis occurs in organisms that reproduce sexually and results in genetically different daughter cells.

    What is the job of a centriole in a cell?

    A:

    Centrioles are tiny cylindrical tubes found in animal cells, and their job is to help organize the structure of microtubules during cell division. Centrioles are located near the cell’s nucleus and are arranged in such a way that they form a “9+3” pattern.
