Q:

What is the function of the plasma membrane?

A:

According to Ohio State University-Mansfield, the cell membrane has many functions, such as compartmentalizing the cell from its environment and protecting the interior of the cell from foreign bodies. The cell membrane is selectively permeable, which means that only certain materials the cell needs to continue to live can come into the cell and waste particles can go out.

The cell membrane also allows the cells to stick to other cells or materials in their world when necessary, and the membrane carries an identity marker that prevents the white blood cells from destroying a body’s own cells.

  • Q:

    Why is the cell membrane important?

    A:

    Cell membranes contain and protect the contents of the cell. They are active in signaling other cells, and proteins embedded in their matrix regulate the cell's chemistry by selectively absorbing and secreting chemicals. Many single-celled organisms, such as amoebae, use their flexible membranes for locomotion and food gathering.

  • Q:

    What is a cell membrane?

    A:

    A cell membrane is a thin layer that acts as a barrier that separates an individual cell or a cellular compartment from other surrounding structures. This dynamic layer plays an essential part in the transport of ions and nutrients.
