NEET2024BotanyCell - The Unit of LifeActual
Mesosome in a cell is a :
Options
- AMembrane bound vesicular structure
- BChain of many ribosomes attached to a single mRNA
- CSpecial structure formed by extension of plasma membrane
- DMedium sized chromosome
Correct answer
C. Special structure formed by extension of plasma membrane
Step-by-step 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.
