Question

The movement by diffusion of charged ions such as Na+ and Cl- across the plasma membrane is blocked by the lipid bilayer in the middle of the plasma membrane. true of false?

Answer 1

True.

Step-by-step explanation:

As we know, the plasma membrane of the cells is semi-impermeable, that is, it only allows the passage of some molecules in sizes and specific burning nature. Although the Na + and Cl- molecules are very small, they are polar, electrically charged molecules. These molecules are not well seen by the membrane, which does not allow them to pass into the intracellular medium.
