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.

Just like skeleton of vertebrates, so is cytoskeleton for Eukaryotic cells. These cytoskeletons are filamentous in nature made up of protein subunits that
WebThough part of the function of the nucleus is to separate the DNA from the rest of the cell, molecules must still be able to move in and out (e.g., RNA). Proteins channels known as nuclear pores form holes in the nuclear envelope. The nucleus itself is filled with liquid (called nucleoplasm) and is similar in structure and function to cytoplasm.
