Cell Membrane In Plant Cell Description
There are other important membranes such as the endoplasmic reticulum ER and the Golgi apparatus.
Cell membrane in plant cell description. The plasma membrane found in all living cells encloses the plant cell and is surrounded by the cell wall. According to this model Cell membrane is made up of. Cell Membrane Job Description.
The cell membrane is present in all living organisms including plants. It is the outermost layer of the cell in animals and encloses other cellular organelles within. Plant cells are eukaryotic cells that vary in several fundamental factors from other eukaryotic organisms.
The cell membrane also called the plasma membrane is found in all cells and separates the interior of the cell from the outside environment. Since plant cell membranes have the sturdy wall they dont need the cholesterol that animal cell membranes use. The plant cell also has several cell organelle structures performing a variety of functions to maintain cellular metabolisms growth and development.
It also allows cells to develop turgor pressure. It separates the cytoplasm the contents of the cell from the external environment. Plants cells have DNA that helps in making new cells hence enhancing the growth of the plant.
Unlike the cell wall the cell membrane is flexible and its shape can be changed as needed. ORGANELLE LOCATION DESCRIPTION FUNCTION cell wall plant fungi and bacteria but not animal outer layer rigid strong stiff made of cellulose support grow tall protection allows H2O O2 CO2 to pass into and out of cell cell membrane both plantanimal All cells plant - inside cell wall animal - outer layer. Images obtained through electron micrography reveal the bilayer structure of cell membranes.
In 1972 two scientists SJ Singer and CL Nicolson proposed fluid mosaic model explaining the structure of the cell membrane. Plants cells contain different varieties of membrane such as the plastids and vacuoles. Cell membrane a thin membrane a double layer of lipids enclosing the cytoplasm of a cell.
