Final answer:
The cell membrane is made of a phospholipid bilayer and is present in all cells. It is also called the plasma membrane and is semi-permeable.
Step-by-step explanation:
TRUE: The cell membrane is indeed made of a phospholipid bilayer. It is composed of two layers of phospholipids, with the hydrophilic (water-loving) heads facing outward and the hydrophobic (water-fearing) tails facing inward.
TRUE: All cells have a cell membrane. It is a vital component of all cells, serving as a barrier between the cell and its environment and regulating the passage of substances in and out of the cell.
TRUE: The cell membrane is also known as the plasma membrane. It is called so because it surrounds and encloses the cytoplasm of a cell.
TRUE: The cell membrane is considered semi-permeable, meaning it allows certain substances to pass through while restricting the passage of others. This selective permeability allows the cell to maintain internal balance and respond to its environment.
