The plant cell parts can be grouped into 3 parts: plant cell wall, cell surface membrane, and cytoplasm (inside which the plant cell organelles are suspended). This is based on how they are seen with a light microscope and electron microscope.The membrane of the plant cell (plasma) functions In plant cells, the cell membrane divides the cytoplasm from the cell wall. It has selective permeability, meaning it regulates the substances that enter and leave the cell. It also provides the cell with support and stability and shields it from external damage.The cell surface membrane creates an enclosed space separating the internal cell environment from the external environment.
