The Golgi complex plays a major role :

  1. as energy transferring organelles
  2. in post translational modification of proteins and glycosidation of lipids
  3. in trapping the light and transforming it into chemical energy
  4. in digesting proteins and carbohydrates

Answer

(2) in post translational modification of proteins and glycosidation of lipids

Solution

As per NCERT, the Golgi apparatus principally performs the function of packaging materials. Proteins synthesised by ribosomes on the ER are modified in the cisternae of the Golgi apparatus before release, and it is the important site of formation of glycoproteins and glycolipids.

Other options: energy transfer – mitochondria; trapping light energy – chloroplasts; digestion – lysosomes.

Why is a capsule advantageous to a bacterium?

  1. It protects the bacterium from desiccation.
  2. It provides means of locomotion
  3. It allows bacterium to "hide" from host's immune system.
