NEET BIOLOGY

Detailed explanation-1: -The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell, and that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell.

Detailed explanation-2: -So, the correct answer is ‘cell wall’

Detailed explanation-3: -Cell membrane It maintains the integrity of a cell and controls passage of materials into and out of the cell. All materials within a cell must have access to the cell membrane (the cell’s boundary) for the needed exchange. The cell membrane is a double layer of phospholipid molecules.

Detailed explanation-4: -The cell membrane is called selectively permeable as it only allows specific molecules to pass. Only specific molecules like water and gaseous molecules can pass through the cell membrane directly. It stops the flow of other molecules towards the two sides.
