Cell membrane
The cell membrane, also known as the plasma membrane, regulates the passage of materials in and out of the cell through the process of selective permeability. Transport proteins and channels embedded in the cell membrane control the movement of substances, facilitating the entry of essential nutrients and the removal of waste products.
Cell membranes serve as a barrier that controls the movement of substances in and out of the cell, allowing the cell to maintain its internal environment. The selective permeability of the membrane also plays a crucial role in communication and recognition between cells. Additionally, cell membranes are involved in cell signaling, adhesion, and are essential for cellular structure and support.
The cell membrane, which is a lipid bilayer, controls the movement of substances in and out of the cell through processes like diffusion, osmosis, and active transport. It acts as a selective barrier, allowing some substances to pass through while blocking others.
The semi-permeable part of the cell would be the cell membrane, which allows some molecules (water, in particular) to pass freely through but restricts the movement of other molecules (such as proteins and enzymes).
The hydrophobic part of the cell membrane helps to repel water, preventing unwanted molecules from passing through. This selective barrier controls what substances can enter and exit the cell, maintaining internal balance and allowing for proper cellular function.

The cell membrane, specifically its lipid bilayer, regulates the passage of substances into and out of the cell through a process called selective permeability. Various proteins embedded in the membrane also assist in facilitating the movement of specific molecules across the membrane.

The phospholipid bilayer. plasma membrane
Plant cells do not have a fully permeable membrane. They have selectively permeable membranes that allow certain substances to pass through while blocking others. This selective permeability helps cells regulate the movement of molecules in and out of the cell.
The cell wall.
the cell membrane is like a guard because it only allows chemicals in and out of the cell
The cell part that allows only certain substances to diffuse into and out of the cell is called the semi permeable membrane. This allows good substances to enter the cell.
The cell membrane is the part of the cell that controls what enters and leaves the cell. It allows nutrients to come in and wastes to move out.
Cell membranes, specifically through channels and transport proteins, regulate the passage of nutrients such as sugar, oxygen, and water into cells and the removal of waste products. This selective permeability ensures that essential substances can enter the cell while harmful substances are kept out.
