∙ 13y ago
It inhibits entrance of harmful substances into the cell due to its selective permeability.
Its pocket like structure called mesoderm performs those functions which are performed by mitochondria in eukaryotes
It has respiratory enzymes.
Retains shape of the cell.
If cell wall is absent, it separates the internal structures and cytoplasm from the external environment.
Prevents the cell from mechanical injury.
Any damage to it causes cell death

Four functions of the plasma membrane?
Four functions of the plasma membrane are:1) Serves as a gateway between the fluid inside and outside the cell. 2) Serves as a communicative device ( for molecules to bind to receptor proteins) 3) Identifies a cell coming from a particular individual. 4) Keeps the cell whole and intact.
The plasma membrance of a cell consists of?
The plasma membrane consists of a phospholipid bilayer that contains proteins. There are four types of proteins in the plasma membrane - structural protein, receptor protein, transport protein and glycoprotien.
What are the four major phospholipids present in the plasma membrane of mammalian cells?
The four major phospholipids present in plasma membrane of mammalian cells are: 1. Phosphatidylcholine 2. Phosphatidylethanolamine 3. Phosphatidylserine 4. Sphingomyelin. For more details click on the link below.
What is the four functions of cell or plasma membrane?
Functions of cell membrane or plasma membrane are-Shape-It provides definite shape to semifluid contents of the cell.Mechanical barrier-It functions as a mechanical barrier that protects the internal contents of the cell.Selectively Permeability-It is a selectively permeable membrane and allows entry of certain substances.Endocytosis-The flexibility of the membrane enables the cell to engulf food and other substances from its external environment by endocytosis. Amoeba acquires its food b this process.Recognition-It has substances over its surface which function as recognition centers and points of attachments. They help in tissue formation, distinction of foreign substances and defence against microbes.Flow of Information-It provides flow of information among different cells of the same organismOsmosis-It occurs due to the presence of tiny water channels in the plasma membrane.Cell Continuity-At places plasma membrane of adjacent cells become continuos to form plasmodesmata and cell junctions.Specialisation-Plasma Membrane gets modified to perform different functions like absorption in microvilli.
What molecules are found in plasma membrane?
The plasma membrane's function is that it allows substances to enter or leave the cell. Its importance is that it acts as a boundary, holding the cell constituents together and keeping other substances from entering. It is found underlying the cell membrane in the cytoplasm and provides a scaffolding for membrane proteins to anchor to. -------------------------- The plasma or cell membrane is made up of a double layer of phospolipid molicules with holes through it made from proteins. For an fuller explanation as to how it is structured etc. look in the related link below phospholipids
Where is the plasma membrane?
Plasma membrane is the same as "cell membrane" it's one of the four characteristics of all cells. So plasma membrane is found "coating" the outside of all cells.

Where is the plasma membrane found?
The cell membrane is the outer boundary of animal cells and plant cells, but plant cells also have a cell wall to protect their cells. The cell membrane and cell walls are the outer boundaries of cells.

What thing existed on earth first?
The first living things on Earth, single-celled micro-organisms lacking a cell nucleus or cell membrane and known as prokaryotes first appeared on Earth almost four billion years ago.
