The cell membrane. And it also gives support to the cell.
A cell membrane, or cell wall.
The plasma membrane is the cellular structure that separates the cytoplasm from the external environment. It is a phospholipid bilayer embedded with proteins that selectively controls the passage of molecules into and out of the cell.

What seperates the internal composition and the Cytoplasme (the liquid inside the cell holding all parts or organisms of the cell in place) of the cell from the external is the plasmic membrane. This membrane has many functions as it's strcuture helps it to move or squeeze into places the cell needs to go.
The cell membrane is the outer boundary of a plant cell that separates its contents from the surrounding environment. Within the cell, membrane-bound organelles such as the nucleus, vacuole, and chloroplasts also help compartmentalize and protect the cell's contents. The cell wall, which is found outside the cell membrane in plant cells, provides additional structural support and protection.
1. It separates cell contents from the external environment. 2. Semi-permeable membrane allowing the passage of substances.
Yes, the plasma membrane acts as a semi-permeable barrier that separates the contents inside the cell from its external environment. It regulates the passage of molecules in and out of the cell to maintain internal balance and protect the cell from potentially harmful substances.
The Cell Membrane forms the outside boundary that separates the cell from its environment.
In cells without cell walls, the cell membrane forms an outside boundary that separates the cell from its environment!
Cells are surrounded by a cell membrane, also known as the plasma membrane. This thin, semi-permeable barrier separates the contents of the cell from its external environment while controlling the passage of substances in and out of the cell.
