NEET BIOLOGY

Detailed explanation-1: -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.

Detailed explanation-2: -Cell membrane or plasma membrane is described as a selectively permeable membrane.

Detailed explanation-3: -In eukaryotic cells, a selectively-permeable membrane is essential for the transport of molecules across the nuclear membrane.

Detailed explanation-4: -Selectively permeable membrane is the one which allows entry of certain substances, exit of some substances but prevents the passage of other substances, through it.

Detailed explanation-5: -The plasma membrane is called as selectively permeable membrane because it regulates the movement of substances in and out of the cell. It means that the plasma membrane allows some material to pass through it while at the same time it blocks other material from entering through it.
