What are functions of cell membranes in the animals cell
1. Protection: The cell membrane acts as a barrier, protecting the contents of the cell from the external environment. It helps to regulate the entry and exit of substances in and out of the cell.
2. Communication: The cell membrane contains receptors that allow the cell to communicate with other cells and respond to signals from outside the cell. This communication is vital for processes such as growth, development, and immune response.
3. Selective permeability: The cell membrane is selectively permeable, meaning it allows only certain substances to pass through while blocking others. This helps to maintain the internal environment of the cell and regulate the movement of ions and molecules.
4. Cell recognition: The cell membrane contains markers that help in cell recognition and identification. These markers play a key role in immune response and cell signaling.
5. Structural support: The cell membrane provides structural support to the cell, helping to maintain its shape and integrity. It also helps in anchoring organelles within the cell and regulating their movement.
6. Transport: The cell membrane contains various proteins and channels that facilitate the transport of molecules and ions across the membrane. This is essential for maintaining cellular homeostasis and carrying out metabolic processes.
