what is the role of the cell membrane in maintaining cellular integrity?
to facilitate the production of atp and other metabolic processes.
to provide energy to the cell and regulate cellular growth.
to store genetic information and control protein synthesis.
to protect the cell from harmful substances and regulate the movement of molecules.
to maintain the cells shape and structure.

Explanation:

The cell - membrane is a selectively permeable barrier. It protects the cell from harmful substances by preventing their entry and regulates the movement of molecules (such as ions, nutrients, and waste products) in and out of the cell, which helps maintain cellular integrity. The other options describe functions of other cell - components or processes. For example, mitochondria are involved in ATP production, DNA stores genetic information, and the cytoskeleton helps maintain cell shape.

Answer:

To protect the cell from harmful substances and regulate the movement of molecules.
