Vedclass · Answer

(D) The bacterial cell envelope consists of three layers: the outermost glycocalyx (slime layer or capsule),the middle cell wall,and the innermost plasma membrane.$1$. The glycocalyx (slime layer or capsule) provides protection and helps in adhesion.$2$. The cell wall determines the shape of the cell and provides structural support.$3$. The plasma membrane is the innermost layer and is selectively permeable (semi-permeable) in nature,controlling the entry and exit of substances in and out of the cell.

The cell envelope is a chemically complex structure consisting of a tightly bound three-layered structure. Which layer is semi-permeable in nature?
