Why is the cell membrane important?

The cell membrane provides rigid support and protection for the cell

The cell membrane structure is semipermeable allowing needed H2O and molecules into the cell.

The cell membrane is not permeable and as a result protects it from intruders like viruses.

The cell membrane is both strong and flexible, allowing cells to work together to build tissues.

The answer is A. The cell membrane provides rigid support and protection for the cell

Explanation:

The semipermeable structure that surrounds the cell helps the cell live in different environments

helicase, i think thats it

in a chemical reaction, the atoms and molecules produced by the reaction are called products. no new atoms are created, and no atoms are destroyed. in a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.
