nothing can pass through it
osmotically active
phospholipids and most proteins to drift about in the plane of the membrane
People live in towns. People are multicellular organisms consisting of trillions of cells. Each cell has a cell membrane.
It's impossible.
Cell membranes contain a variety of biological molecules, notably lipids and proteins. Material is incorporated into the membrane, or deleted from it, by a variety of mechanisms:Fusion of intracellular vesicles with the membrane (exocytosis) not only excretes the contents of the vesicle but also incorporates the vesicle membrane's components into the cell membrane. The membrane may form blebs around extracellular material that pinch off to become vesicles (endocytosis).If a membrane is continuous with a tubular structure made of membrane material, then material from the tube can be drawn into the membrane continuously.Although the concentration of membrane components in the aqueous phase is low (stable membrane components have low solubility in water), there is an exchange of molecules between the lipid and aqueous phases.
osmotically active
yes, it is
It contains proteins, which are ribosomes, and the E.R.YHURRR WELCOME!!!! I'm mean please say thanks :)
well i wouldn't say yes, because a cell membrane is more of a gate.
It is usually the cell membrane i think. But the nucleus is "the brain" of a cell. But i would say the cell membrane. hope this helps.
Yes.
You could say it is contiguous with the nuclear membrane as it is attached to this membrane and surrounds it.
A cell membrane is a semi-permeable membrane that surrounds the cytoplasm of a cell, providing structure and controlling the movement of substances in and out of the cell. It is primarily composed of lipids and proteins that help maintain the cell's internal environment and interact with the external environment.
an average animal cell is round and it contains a cell membrane cytoplasm and a nucleus which has the code for the DNA.
phospholipids and most proteins to drift about in the plane of the membrane
the cell membrane prevents the nucleus cytoplasm and ...etc not to leak out of the cell .so it is a wall that keeps every thing inside the cell.EX:lets say its like a water balloon that keeps the water inside the balloon.
I would say the cell wall...
