Question

Which part of the cell membrane is polar and allows the cell to exist in water

Answer 1

Answer:

The Phospholipid head which contains a phosphate group

Explanation:

The cell membrane contains phospholipids.

The Phospholipid bilayer is made up of phospholipids

Phospholipids consist of a hydrophobic tail (non-polar and is repelled by water)

It also consists of a polar head which is polar because it has a phosphate group which is negatively charged and therefore is hydrophilic (water-loving)

Answer 2

Phosphate groups are polar and allow the cell to exist in water.
