Yes. All cells have a cell membrane.
If I remmember this correctly, then the cel membrane is kinda like a small protection, and it's thin enough to let food etc. pass
The student observed a eukaryotic cell under the microscope. Eukaryotic cells have a defined nucleus enclosed by a membrane and other membrane-bound organelles, distinguishing them from prokaryotic cells.
The part of the cell that controls what goes in and out is the cell membrane, also known as the plasma membrane. It is a selectively permeable barrier composed of a lipid bilayer with embedded proteins that regulate the movement of substances. This structure allows essential nutrients to enter the cell while keeping harmful substances out, maintaining the cell's internal environment.

Cell MembranesWe have been talking about cells being a unit of organization in biology. Let's look at the cell membrane and see how that membrane keeps all of the pieces inside
The cell membrane controls what goes in and out of the cell. It is a selectively permeable barrier that allows certain substances to pass through while preventing others from entering or leaving the cell. This helps maintain the internal environment of the cell.

In a cell, positively charged ions move across the cell membrane, creating an electrical potential difference. This potential difference results in an action potential travelling along the cell. The movement of ions across the membrane is facilitated by ion channels and ion pumps, which regulate the flow of ions in and out of the cell.

The outer covering of a plant cell is called the cell wall. It provides structure and support to the cell, allowing it to maintain its shape and protect the cell from damage. The cell wall is primarily made of cellulose, a strong and rigid carbohydrate polymer.
