the cell membrane
The cell wall
Animal cells don't have cell walls. Only plant cells do - they are rigid to help keep the shape of the cell. Both plant and animal cells have cell membranes which are flexible and are meant to regulate what goes into the cell.
Cell membrane
The flexible covering around a cell is called the cell membrane. This membrane acts as a barrier and regulates the movement of substances in and out of the cell, helping to maintain the cell's internal environment. It is composed of a phospholipid bilayer embedded with proteins.
the cell membrane is as flexible barrier outside of the cell.
The flexible outer layer of the cell is called the cell membrane. It is a semi-permeable barrier that surrounds the cell, controlling the passage of substances in and out of the cell.
ANimal cells. They dont have a cell wall so it makes them very flexible.
parenchyma
The thin flexible membrane around all cells is called the cell membrane or plasma membrane. It serves as a protective barrier that regulates the passage of substances in and out of the cell.
A flexible membrane.
the answer is the cell membrane
the cell membrane
The thin, flexible barrier around a cell is called the cell membrane. It regulates the flow of materials in and out of the cell and helps maintain the cell's shape and integrity.
The cell wall
The cell membrane moves in a fluid motion due to cholesterol lined between the phospholipids that make up the cell membrane. This allows for freer movement of the cell.
