Cytoskeleton structure and function|Microfilament| Microtubules|Intermediate structure

The cytoskeleton is the network of fibres forming the eukaryotic cells, prokaryotic cells and archaeans. These fibres in the eukaryotic cells contain a complex mesh of protein filaments and motor proteins that help in cell movement. It provides shape and support to the cell, organizes the organelles and facilitates transport of molecules, cell division and cell signalling. cytoskeleton structure comprises the following types of fibres: Microfilaments Microtubules Intermediate Filaments Microtubules Microtubules appear like small, hollow, round tubes with a diameter of about 24 nanometers. They are made up of a protein, tubulin. Thirteen tubulins link to form a single tube. Microtubules are very dynamic structures, which reveal that they can change quickly. They keep growing or shrinking steadily. These help in transporting cellular materials and dividing chromosomes during cell division. Microfilaments Microfilaments are thread-like protein fibres, 3-6 nm in diameter. They are particularly found in muscle cells. They consist of the protein actin, responsible for muscle contraction. These are also responsible for cellular movements including cytokinesis, contraction, and gliding. Intermediate Filaments The intermediate filaments are about 10 nm in diameter and provide tensile strength to the cell. They facilitate the formation of keratins and neurofilaments. keywords -cytoskeleton class 11, cytoskeleton structure and function, cytoskeleton csir net, cytoskeleton bsc 1st year, cytoskeleton animation, cytoskeleton bsc 1st year zoology, cytoskeleton in hindi, cytoskeleton class 11 biology, cytoskeleton diagram, cytoskeleton by ritu rattewal    • CAM pathway| crasaulacean acid metabolism|...   #cytoskeleton #eukaryoticcell #plantcell #animalcell #cell #cellcycle #celldivision #csirnet #dbt #iitjam #iiscbangalore #iit #neet #nitrogen #concept #gate #jrf #cbse #biology #class12 #class11 #bsc
