Detailed explanation-1: -What is Cytoskeleton? 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.
Detailed explanation-2: -There are three groups of movers, the motor proteins: kinesin, dynein and myosin, and three main groups of shapers, the protein filaments: microtubules, intermediate filaments and actin filaments.
Detailed explanation-3: -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.
Detailed explanation-4: -The cytoskeleton is a complex, dynamic network of interlinking protein filaments present in the cytoplasm of all cells, including those of bacteria and archaea.
Detailed explanation-5: -The cytoplasm consists of everything inside the cell membrane of the cell, excluding the nucleus in a eukaryotic cell. The cytoskeleton is a cellular “skeleton” that crisscrosses the cytoplasm. The three main cytoskeleton fibers are microtubules, intermediate filaments, and microfilaments.
