The plasma membrane is made or phospholipids which contain a hydrophobic tail and a hydrophillic tail. In order to maintain stability the tails will attract the heads will be attracted to water which is found in both the cytosol and extracellular space. This causes a spontaneous formation of a bi-layer in which two phospholipids are stacked to prevent loss of fluid from the cell or vesicle.
What else can I help you with?
Plasma cells develop from transformed b cells or t cells?
ativated B cells forms effector cells which are called plasma cells
Where do plasma cells arise from?
Plasma cells arise from B cells during the immune response. B cells differentiate into plasma cells in response to antigen stimulation, and plasma cells are responsible for producing and secreting antibodies to fight off pathogens.
What does the plasma membrane do?
The plasma membrane is like the skin of the cell and lets only certain things in and out. It uses active and passive transport to let things in and out meaning that it uses energy only sometimes to let things in and out (this being active) and lets things move as they please at other time (this being passive)
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.
Are plasma cells specialized B cells?
Yes, plasma cells are specialized B cells. They are derived from B cells and are responsible for producing and secreting antibodies or immunoglobulins in response to an antigen. Plasma cells are a critical component of the immune system's humoral response.
A typical bacterium cell can be described as?
B: a cell wall surrounding a plasma membrane filled with ctoplasm with circular DNA and inclusions, but no membrane bound organelles.
Foreign antigens pressed into the plasma membrane are recognized by what?
helper T cells B cells so the answer is B for Plato users
The cytoplasmic structure in a bacterial cell is the a. cell wall b. nucleoid c. plasma membrane d. ribosomes?
b-nucleoid
What is the difference between antibody and immunogloulin?
Antibodies are secreted (plasma cells), while immunoglobulins are membrane-bound (naive B cells).
What are the 3 major parts of cell?
cell membrane, cytoplasm, and organelles
A person whose blood genotype is IAi has red blood cells with antigens bound to the outer membrane surface and anti- antibodies floating in the plasma?
A; B
T cells and B cells activated only by what?
T cells are activated by antigens presented on the surface of antigen-presenting cells, such as dendritic cells. B cells are activated primarily by recognizing antigens with their B cell receptor, although they may also require T cell help for full activation.
Plasma cells develop from transformed b cells or t cells?
ativated B cells forms effector cells which are called plasma cells
Plasma cells develop from transformed t or b cells?
The plasma cells develop from transformed b cells.
Where do plasma cells arise from?

Cells of many protists plants and fungi but not animals commonly have a. Mitochondria b. a plasma membrane c. a cell wall d. ribosomes?
c. a cell wall
