What part of the cell membrane is polar and allows cells to exist in water?
Phosphate groups

Phosphate groups
What part of the cell is polar and allows the cells to exist in water?
Phosphate groups
What is a permeable membrane?
permeable membrane: is a membrane that allows water to pass through the membrane ; the salt water is then left out
What characteristics of a water molecule causes its attraction to a cell membrane?
Water molecules are polar This causes them to be attracted to the cell surface, which is also polar in nature

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 .
What are the substances that the cell membrane does not allows to pass?
Usually Ions and charged molecules (salts dissolved in water), large polar molecules (glucose), and macromolecules.
What allows water to cross the permeable membrane of an animal cell?
plasma membrane allows water to enter animal cell
