The cell membrane is also known as the plasma membrane due to its role as a semipermeable barrier that separates the cell's internal environment from the external environment. It is composed primarily of phospholipids and proteins that help regulate the passage of substances in and out of the cell.
Prostoglandins are lipidic substances.
No, the cell membrane does not remove waste from the cell. Waste removal is typically carried out by other organelles within the cell, such as lysosomes or vacuoles, or by the cell expelling waste through processes like exocytosis. The main function of the cell membrane is to regulate the passage of substances into and out of the cell.
Cells that are responsible for absorbing nutrients, like epithelial cells in the intestines, may form a filtering membrane to selectively allow certain substances to pass through. Additionally, cells in the kidneys, such as renal tubular cells, help in filtering blood to remove waste products. Protective cells, such as those in the skin or mucous membranes, act as physical barriers to pathogens and harmful substances.

A transport protein is a type of protein that is involved in moving substances such as ions, molecules, or macromolecules across a biological membrane. These proteins play a crucial role in maintaining the necessary balance of substances inside and outside of cells, ensuring proper cell function and communication.
The flexible outer boundary of the cell is called the cell membrane or plasma membrane. It acts as a barrier, controlling the movement of substances in and out of the cell. The cell membrane is composed of a double layer of phospholipids with embedded proteins.
