Yes, the cell membrane is selectively permeable, meaning it allows certain substances to pass through while blocking others. This is essential for controlling the movement of molecules in and out of the cell to maintain internal balance.

Two jobs for the cell membrane are to keep things out that should not be there and to allow only a few special things in.
The cell membrane, composed of a phospholipid bilayer, helps maintain homeostasis by selectively allowing substances to enter or exit the cell through processes such as diffusion, osmosis, and active transport. This helps regulate the cell's internal environment and ensure proper functioning.
Things can pass in and out through the cell.
The cell membrane is semipermeable, meaning it can let some things through but not others. This membrane keeps many things out, protecting the cell, while at the same time allowing certain things through that the cell may need or need to eliminate.

To let things through the cell membrane
The cell membrane regulates the passage of substances in and out of the cell, provides structure and support to the cell, and helps in cell communication and recognition.

Molecules can not pass through the cell membrane, because endocytosis is important for those large molecules that can not pass through the cell membrane!!
