    Is point 10 correct?

    Microtubules help in formation of various structures like Cilia flagella, basal body & centrioles (point 7). How can microtubules help in fixing cell organelles?

    Microfilaments should be responsible for fixing cell organelles, isn't it?

    In point 7 it is written microfilaments formed extensive network in the cytoplasm. Please explain.

    They also function as routes along which organelles can move throughout the cytoplasm. Microtubules are typically found in all eukaryotic cells and are a component of the cytoskeleton, as well as cilia and flagella.
    Microtubules are conveyer belts inside the cells. They move vesicles, granules, organelles like mitochondria, and chromosomes via special attachment proteins. They also serve a cytoskeletal role.



  • @anag
    Microfilaments, also called actin filaments, are polymers of the protein actin that are part of a cell's cytoskeleton. The cytoskeleton is the network of protein filaments that extends throughout the cell, giving the cell structure and keeping organelles in place.



  • @sunitasaxena if microtubules form the skeleton of the cell, what is the utility of microfilaments?

    Do both microfilaments and microtubules give the cell a proper structure and keep the cell organelles in a proper place? Both of them have same function?



  • @anag
    All of the microfilaments and microtubules combine to form the cytoskeleton of the cell.
