Cell Membrane In Plant Cell Description
Cell Membrane Functions The most important membrane in animal cells is the plasma membrane.
Cell membrane in plant cell description. Since plant cell membranes have the sturdy wall they dont need the cholesterol that animal cell membranes use. The cell membrane is flexible allowing plant cells to survive in less than optimal environmental conditions such as when plants wilt from a lack of water. It separates the cytoplasm the contents of the cell from the external environment.
In plant cells the membrane encapsulates the protoplasm. Cell Membrane is the second layer in plant cell present below the cell wall while in animal cell it is the first layer. 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.
In 1972 two scientists SJ Singer and CL Nicolson proposed fluid mosaic model explaining the structure of the cell membrane. The plant cell also has several cell organelle structures performing a variety of functions to maintain cellular metabolisms growth and development. The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress.
The cell membrane is present in all living organisms including plants. Cell membrane a thin membrane a double layer of lipids enclosing the cytoplasm of a cell. The cell membrane also called the plasma membrane is a thin layer that surrounds the cytoplasm of all prokaryotic and eukaryotic cells including plant and animal cells.

The cell membrane regulates the transport of materials entering and exiting the cell. 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. In plant cells the membrane encapsulates the protoplasm.
