Selective Permeability
What else can I help you with?
What is the main fuction of the plasma membrane?
The main function of plasma membrane is to regulate things in or out of the cell cytoplasm by osmosis,active diffusion,passive diffusion,endocytosis,ectocytosis etc because it acts as selectively permeable membrane.Plasma membrane forms a barrier between the interstitial fluid and inside cell environment. It is selectively permeable. Plasma membrane has trans membrane proteins embedded in it.
Does the plasma membrane allow all substances to pass into and out of the cell?
No, the plasma membrane is semipermeable, meaning it allows some substances to pass through while blocking others. This selectivity is crucial for maintaining cell function and regulating the internal environment of the cell.
What organelle helps the cell keep its shape and determines what goes in and out of the cell?
The cell membrane, also known as the plasma membrane, is the organelle that helps the cell keep its shape and determines what goes in and out of the cell. It acts as a semi-permeable barrier, regulating the flow of molecules in and out of the cell.
What are the importance of plasma membrane?
It controls what enters and leaves the cell, provides protection and separation for that cell, and provides a shape for the cell. It gives an anchoring point for the cytoskeleton and the cell wall (if appliccable) and can be involved in cell signalling pathways, which direct the cell to do things, or not to do things.
Is cytoplasm in plasma membrane?
Well some thing has to keep the cyto [cell] plasm [fluid] within the cyto [cell]. A membrane [containment] could would act as a wall covering the surface and retaining the overall viscosity on the inside surrounding the cells nucleus. Keep in mind that the membrane is still a two way perimeter letting certain things into the [cyto] and passing certain substances out, based upon the need for keeping a balance and maintaining appropriate homeostasis. the membrane responds to both active an d passive transport.

Controls what goes in and out of the cell?
It is the cell membrane. As the name indicates it is the membrane around the cell which has exactly the function described, controlling what is going in and out of the cell, through different kinds of channeling technics

What controles the movement in and out of the cell?
Inside of a cell it is the cell membrane which lets substances pass into the cell, and out. The cell wall is used to keep the shape of the cell the same.
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
What is the composition and function of each structure of the plasma membrane?
it is mostly water with many dissolved solute such as: nutrient, gases, hormones and wastes. Most plasma protein are produced by the liver. Albumin which is 60% of plasma protein serves as blood buffer to plasma osmotic pressure( the pressure that helps to keep water in the bloodstream). Another function of is plasma distribute heat.
What is the function (job) of lipids?
That is just another name for the cell membrane. It's main job is to keep the things that are on the inside of a cell inside, and keep what things are outside the cell on the outside. It is also called a semipermeable membrane because it can allow some things, under certain situations, to cross the phospholipid bilayer to enter or exit the cell.The phsopholipid bilayer is the thin polar cell membrane comprised of two layers of lipids. This membrane surrounds a cell to keep substances (ions, proteins, etc) in or out of the cell, but also allow selected substances to pass through the cell membrane as required.
Do peroxisome have membrane?
Yes, peroxisomes have a single membrane that surrounds their structure. This membrane helps to separate the contents of the peroxisome from the rest of the cell and plays a role in maintaining the organelle's function.
What lipids forms a bilayer between watery region in the plasma membrane of a cell?
I believe you are referring to phospholipids. They form a bilayer around the plasma membrane of the cell to keep the cellular contents in and selectively allow things to come in and out of the cell.
