Mesosome in a cell is a :

Mesosome in a cell is a :
  1. Membrane bound vesicular structure
  2. Chain of many ribosomes attached to a single mRNA
  3. Special structure formed by extension of plasma membrane
  4. Medium sized chromosome

Solution

Mesosomes are formed by the extensions of plasma membrane into the cell. Thus, option (3) is correct. Lysosomes are membrane bound vesicular structures. Thus, option (1) is incorrect. Several ribosomes may attach to a single mRNA and form a chain called polyribosomes. Thus, option (2) is incorrect.
