A Worm
The thin structure that surrounds the cytoplasm of a cheek cell is called as cell membrane. This is present in most plant, animal and fungi cells. It is a selectively permeable structure and allows the flow of ions and particles from the inside of the cell to the outside and vice-versa.
The outside of an animal cell is covered by a plasma membrane, a thin barrier made up of lipids and proteins. This membrane controls the movement of substances in and out of the cell, allowing the cell to maintain its internal environment and communicate with its surroundings.
The thin outer covering of an animal cell is called the cell membrane. It is a semi-permeable membrane that controls the movement of substances in and out of the cell.
The thin outer covering of an animal cell is called the plasma membrane. It serves as a barrier that regulates the passage of substances in and out of the cell.
Cell membrane
The thin structure that surrounds the cytoplasm of a cheek cell is called as cell membrane. This is present in most plant, animal and fungi cells. It is a selectively permeable structure and allows the flow of ions and particles from the inside of the cell to the outside and vice-versa. However plant cells, in addition to the cell membrane also have the cell wall outside the cell membrane. This provides mechanical rigidity to the cell and prevents the flow of larger particles.
