Cell membranes come into contact with water throughout the human body. The cell membrane comes into the most contact with water in the bladder, which holds urine that is mainly composed of water.

Molecules A and B come in contact with the cell membrane of the same cell Molecule A passes through the cell membrane readilybut molecule B does not Which statement could describe molecules A an?
molecule A is a SImple Sugar WHile B Is Starch
What part of the cell membrane is polar and allows the cell to exits in water?
The cell membrane is made out of two layers , a nonpolar and polar part. The polar part is the hydrophilic part , meaning water loving , and the nonpolar is hydrophobic part - water hating. The polar/hydrophilic part is inside of the membrane and the outer portion is the hydrophobic/nonpolar . You don't want the cell to exist in water or be soluble in water because then we would dissolve , all our cells , tissues etc. That's why the cell membranes outer portion is nonpolar and is not miscible with water . The cell membrane allows water molecules to come in and out of the cell by osmosis , and that is when water molecules can free out and in of the cell through the cell membrane .
Do water molecules passively enter and leave cells through the plasma membrane?
Yes, the direction of the flow depends on the contentration of water on the out side and the inside of the cell's membrane.
What are the outer layer of a human red blood cell?
The outer layer of an animal cell is called the cell membrane. It controls what can go into and come out of the cell.
What would happen if the plasma membrane ruptures or break down?
Plasma Membrane is the outer covering of the cell that seperates its content from the surrounding medium. It is a selectively permeable membrane . If it rupture or breaks down the cytoplasm will come in direct contact with the surrounding medium and the act of selection will stop.
What structure in a plant cell may force the cell membrane into contact with the cell wall?
The structure in a plant cell that may force the cell membrane into contact with the cell wall is the plasma membrane. This will also come into contact with the vesicle membrane.
Where does a cell come into contact with water?
vacuole

How does the cell membrane help the plant cell?
The Cell Membrane helps the plant cell by guarding any viruses that come near it.
Why the human membrane made out of lipids?
The human cell membranes are made out of lipids because lipids propel water, and if it weren't made out of liquids, every time we come in contact with water we would either shrink or grow in big amounts.
What happens when you put a egg in salt water?
The egg should have its water or substance in the egg come out through the cell membrane. :)

Yes, the direction of the flow depends on the contentration of water on the out side and the inside of the cell's membrane.
How does the cell membrane help the cell?
It lets authorized objects come in and out of the cell to protect it

What are some functions of the cell membrane that's in all cells?
the cell membrane allows materials, such as bacteria, to come in or out.It is the outside boundary of the cell that separates the cell from its envornment.
