Q. Mesosomes are the infoldings of cells membrane, which I. helps in cell wall formation, DNA replication and respiration II. increases the surface area of plasma membrane III. are present in both prokaryotic and eukaryotic cells Choose the correct option
A) II and III
B) I and II
C) I and III
D) I, II and III
Explanation
A special membranous structure is the mesosome which is formed by the extensions of plasma membrane into the cell. There extensions are in the form of vesicles, tubules and lamellae They help in cell wall formation, DNA replication and distribution to daughter cell. They also help in respiration and secretion processes to increase the surface area of the plasma membrane and enzymatic content
