This means that the plasma membrane allows the entry of some substances while preventing the movement of some other substance.

. Plasma membrane allows some materials to pass through it while blocks other materials from entering through it. Some molecules such as hydrocarbons and oxygen can cross the membrane. The cell membrane is said to be selectively permeable because it lets certain substances pass through while restricting the passage of others.

The membrane is selectively permeable because substances do not cross it indiscriminately. Water can pass through between the lipids. Answer- Plasma membrane called a selectively permeable membrane because it regulates the movement of substances from within to outside of the cell.

The actual structure of the cell membrane allows free passage or restricts movement of substances across the membrane. Membranes also have many embedded proteins Each phospholipid has a hydrophilic head that is attracted to water. Many large molecules such as glucose and other sugars cannot.

Selectively permeable Cimpermeable Dexclusively lipid-soluble. Why is the cell membrane described as selectively permeable. A cell membrane the outer casing or inner casing in a plant cell is selectively permeable because some materials can pass freely through the.

The membrane is selectively permeable because substances do not cross it indiscriminately. The movement of water across a selectively permeable membrane from high to low water concentration. Answer- Plasma membrane called a selectively permeable membrane because it regulates the movement of substances from within to outside of the cell.
