Cell Membrane In Plant Cell Description
In the case of the plant cells, besides the cell membrane, there is also an outer thick layer that is known as the cell wall.
Cell membrane in plant cell description. However, the cell wall acts as a solid mechanical support only. Cell membrane synonyms, cell membrane pronunciation, cell membrane translation, english dictionary definition of cell membrane. Also called cytomembrane , plasmalemma , plasma membrane.
When you think about a membrane, imagine it is like a big plastic bag with some tiny holes. 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. One of the distinctive aspects of a plant cell is the presence of a cell wall outside the cell membrane.
However, unlike the plasma membrane (which is present in all cells), a cell wall is only found in some organisms (e.g. Controls the passage of substances in and out of the cell surrounds and protects the cell and its organelles nucleus description: Cell membrane, thin membrane that surrounds every living cell.
Plants, some bacteria, and fungi among a few others). In plant cells, the membrane encapsulates the protoplasm. Cell membrane 1 cell membrane.
A cell membrane physically separates the contents of the cell from the outside environment, but in plants, fungi and some bacteria, there is a cell wall that surrounds this membrane. It is made up of proteins and lipids and often contains molecular receptors. The cell membrane functions as a barrier, keeping cell constituents in and unwanted substances out, and as a gate, allowing transport into the cell of essential nutrients and movement from the cell of waste products.
It is a feature of all cells, both prokaryotic and eukaryotic. Controls the passage of substances in and out of the cell surrounds and protects the cell and its organelles nucleus description: Images obtained through electron micrography reveal the bilayer structure of cell membranes.
