Which one of the following organelles is located near the nucleus and contains a collection of flattened membrane bound cisternae? (a) Nucleolus (b) Mitochondrion (c) Centriole (d) Golgi apparatus
Option a The two poles of a Golgi apparatus are called cis face and trans face, which act respectively as the receiving and shipping departments. The vesicles lie near the ends and concave surface of the Golgi complex. They are pinched off from the tubules of the cisternae. They are of two types : smooth or secretory vesicles, which have a smooth surface and contain secretions of the cell; and coated vesicles, that have rough surface and elaborate membrane proteins. They carry materials to or from the cisternae. The Golgi complex gives rise to primary lysosomes by budding from the trans face of cisternae.
