Question
Describe structure and functions of Golgi apparatus.

Answer

Structure of Golgi apparatus: Golgi apparatus first described by Camillo Golgi. There are three distinct components are visible in the Golgi complex. They are:
  • Flattened sacs or cisternae.
  • Clusters of tubules and vesicles.
  • Large vesicles or vacuoles.
Golgi apparatus has a convex forming face and a concave maturing face. The forming face receives vesicles from $ER$ and maturing face produces secretory vesicles and lysosomes. Golgi apparatus absent in bacteria, blue green algae, mature sperms and $RBC$ of mammals and other animals.
Function:
  1. The main function of Golgi apparatus is secretory. It helps in the secretion of mucus, enzymes and hormones.
  2. It helps in the storage of secretory products.
  3. Golgi apparatus is also involved in the synthesis of cell wall, plasma membrane and lysosomes.

A sound producing body is at considerable distance from a man. There can be four different media $W, X, Y$ and $Z$ between the sound producing body and the man. The medium $X$ brings the sound to man most quickly whereas medium $Z$ takes the maximum time. The time taken by medium $W$ in bringing sound to man is less than that of $X$ but more than that of $Z.$ The medium $Y,$ however, fails to bring the sound from the sound producing body to the man. Which medium could be the one:
