The characteristic that a plasma membrane bears is the semi-permeability. This is what keeps certain materials in while keeping certain materials out.

What is the function of a cell selectively permeable plasma membrane?
it regulates what materials enter and leave the cell
What are function of membrane proteins?
Membrane proteins have a variety of functions. They relay signals between the cell's inside and outside environments. Transport proteins move the molecules across the membrane.
A vacuole carrying waste materials from a cell fuses with the inside surface of the cell's plasma membrane the waste materials are then released to the medium outside of the cell?
exocytosis. :)
What is a membrane covered compartment that makes lipids and other materials for use inside and outside the cell?
EndoPlasmic Reticulum
Controls the movement of molecules into and out of the cell?
To put it simply, it is the cell membrane. You can have transport vesicles ect, but the cell membrane is the main barrier between inside and outside. It contains pumps, channels and proteins that are in charge of communication and also control movement of everything from inside and outside. hhh
Compared to the inside of the resting plasma membrane the outside surface of the membrane is?
The outside is slightly positive while the inside is slightly negative.
What is the area outside the nuclear membrane but inside the cell membrane?
Cytoplasm
What is the cell membrane and what is its function?
The cell membrane is a protective layer that protects the cell inside of it.
What is the cell membrane and what is the function?
The cell membrane is a protective layer that protects the cell inside of it.
How does the structure of the plasma membrane allow materials to move across it in both directions?
The structure of the plasma membrane consists of the phospholipid bilayer, which gives it a fluid structure, and not rigid, allowing the materials ease to pass through. Next, there are also integral proteins which can be thought of as 'tunnels', allowing the materials to come in and out. Then, there are peripheral proteins which also aid in getting the materials inside an out. On the cell membrane, there are receptors which recognize outside materials, and if they are really big, the cell engulfs these molecules through endocytosis [pinocytosis, and phagocytosis, which are basically for liquid molecules, and solid molecules]. This takes us back to the fluidity of the cell membrane. That's roughly how the cell membrane allows for the entering and exiting materials.
Does cell body mean cell membrane?
The function of the cell membrane is to allow certain substances to enter and exit the cell. The cell membrane forms a barrier between the inside of the cell and the outside, so that the chemical environments on both sides can be different. It regulates the movement of materials into and out of the cell. The body of the cell is the cell as a whole whether it is a plant with a cell wall or animal cell.
Is cell membrane is an organelle?
No. It has a function to maintain the difference between the inside and the outside of the cell is not considered an organelle (little organ).
