Cell Membrane In Plant Cell Description
It separates the cytoplasm the contents of the cell from the external environment.
Cell membrane in plant cell description. Cell Membrane Job Description. Images obtained through electron micrography reveal the bilayer structure of cell membranes. In plant cells the membrane encapsulates the protoplasm.
Plant-like cells have a cell wall as the first layer of protection and the structure of this wall is very rigid. Its function is to protect the integrity of the interior of the cell by allowing certain substances into the cell while keeping other substances out. All membranes whether external or internal are now called cell membranes or bio membranes.
In plant cells the membrane encapsulates the protoplasm. The plant cell also has several cell organelle structures performing a variety of functions to maintain cellular metabolisms growth and development. One of the distinctive aspects of a plant cell is the presence of a cell wall outside the cell membrane.
The membrane as a secondary protection area and its found inside the cell wall. There are other important membranes such as the endoplasmic reticulum ER and the Golgi apparatus. Average thickness is 75 A 50100 A.
Both plant and animal cells contain nucleus along with similar organelles. Plant cell structures see below for key to numbering Source. The cell membrane also called the plasma membrane is found in all cells and separates the interior of the cell from the outside environment.
The cell membrane plasma membrane is a thin semi-permeable membrane that surrounds the cytoplasm of a cell. It also allows cells to develop turgor pressure. In 1972 two scientists SJ Singer and CL Nicolson proposed fluid mosaic model explaining the structure of the cell membrane.
