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: -The most important thing about membranes is that they regulate what moves in and out of a cell. The membrane is selectively permeable because substances do not cross it indiscriminately. Some molecules, such as hydrocarbons and oxygen can cross the membrane.

Detailed explanation-4: -The cell membrane is semipermeable (or selectively permeable). It is made of a phospholipid bilayer, along with other various lipids, proteins, and carbohydrates.

Detailed explanation-5: -Definitions: The semipermeable membranes permit the movement of solvent molecules through them but prevent the movement of solute particles. The selectively permeable membrane are normally semipermeable but allow selective passage of solutes through them.
