Usage: technical; biology; also called cell membrane or plasma membrane

Examples

• The plasmalemmas of adjacent cells are separated by a narrow space called the intercellular space.
• Proteins embedded in the plasmalemmas regulate the transport of nutrients into the cell.
• Under the electron microscope, the plasmalemmas appear as thin, dark lines surrounding each cell.
• The integrity of plasmalemmas is essential for maintaining cellular homeostasis.
• Damage to the plasmalemmas can lead to cell death or dysfunction.
