Question

Besides giving out secretory vesicles, the Golgi apparatus is also concerned with the formation of

• A. lysosomes
• B. plastids
• C. grana of chloroplasts
• D. cell plates after cell division in plants.

Answer 1

Answer: (A)

lysosomes

Answer 2

The Golgi apparatus is present in all eukaryotic cells. It is specially extensive in the secretory cells. It is a central stack (pile) of parallel, flattened, intercommunicating sacs or cistemae and many peripheral tubules and vesicles. 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 cistemae. 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 cistemae. The Golgi complex gives rise to primary lysosomes by budding from the trans face of cistemae.
