Cytoskeleton structure and function ppt
WebCytoskeleton. Functions as structural support cell movement movement of vesicles within cells. It is present within the cells of all four eukaryotic kingdoms Protista, Fungi, Plantae, … WebStructure: hair-like organelles that extend from the surface of cells. When they are present in large numbers on a cell they are called cilia. When they are less numerous and longer they are called flagella. Both organelles are composed of nine pairs of microtubules arranged around a central pair. Function: cell motility.
