What is a plasma membrane made of?
A plasma membrane is made of a phospolipid bi-layer. Think of a plasma membrane like a grilled cheese sandwich. The bread on the outside of the sandwich is similar to the polar head of the plasma membrane, and the cheese on the inside is similar to the fatty tails on the inside of the membrane. If you tried to run water through the grilled cheese sandwich it would not get through the cheese center, much like water will not get through the center of a plasma membrane.
How much glycoproteins are in the cell membrane?
there are 2% of the molecules in plasma membrane and 50% of its weight these are the protins in the animal cells.
How does the plasma membrane maintain homeostasis?
The Plasma membrane maintains the homeostasis throughout a cell because it filters what substances go in and out of the cell. If there is too much of a substance in a cell the plasma membrane quickly disposes it and when there is not enough of a substance in a cell the plasma membrane lets the substance in.The plasma membrane uses selective permeability to maintain homeostasis in a cell by eliminating wastes and taking in needed items.
How does temperature correlate to the permeability of the cell membrane?
Cell membranes act very much like a fluid on a molecular level. The phospholipids move around each other with relative ease, making the membrane flexible. With an increase in temperature, the molecular movement will increase throughout the membrane thus leading to looser fits among molecules and a more permeable membrane.
What is the function of the cell plasma membrane?
The plasma membrane serves as a barrier to the outside environment. The membrane acts as a boundary, holding the cell constituents together and keeping other substances from entering.The plasma membrane surrounds the outside of both Eukaryotic and Prokaryotic cells. It is made up of a double layer of phospholipids and controls the movement of various substances into and out of the cell, both passively and actively. It also allows cell identification.my mommy and your mommy !1. Transport2. Enzyme Activity3.

Plasma membrane like what in your body?
Skin. Like plasma membrane, the skin protects us from external harm (although the skin a much better barrier). It is also a covering of the cell, much how our skin is covering our body.
What does it mean to be selectively permeable semi-permeable?
DefinitionnounA membrane that is selectively permeable, i.e. being permeable to only certain molecules and not to all molecules.SupplementAn example of such membrane is the cell membrane wherein it allows passage of only certain types of molecules by diffusion and occasionally by facilitated diffusion.by~paula razon (facebook)!!!

What fills the space between cell wall and membrane after plasmolysis?
The cell membrane is a selectively permeable membrane that will only let water and solutes across it. The cell membrane freely allows pretty much everything to pass across it, meaning that things unable to pass the membrane back up and push it away from the cell wall. Therefore the gap is filled with the SUGAR SOLUTION that is surrounding the cell.

What is the out cell membrane do in a plant cell?
it is not call ed the outer membrane, its the cell wall. It does the same thing like the cell membrane, but the cell wall is much for stricter with objects coming in and out of cell, what is call, selectivly permeable
What do you think will happen to the the cell if the plasma membrane does not function properly?
It will burst, or shrivel. The plasma membrane(Cell Membrane) manages what goes in and out. If it doesn't function properly, it will either take in too much water, take out too much water or make no changes. Takes in too much > Burst. Takes out too much > Shrivel. Stays the same > Eventually runs out of nutrients and dies.

Does lympth or plasma have more proteins?
Plasma has much more proteins than lymph.

How does Equilibrium help osmosis?
Osmosis is a phenomenon that helps cells reach equilibrium. If you have a membrane that's only permeable to water and not to, say, a certain solute...and you have too much of the solute on one side, water flows passively to that side. That way, it can make the concentrations on both sides of the membrane more equal.
