which statement about the cell membrane is true?\nit contains cellulose and sugars that are involved in communication.\nit is present in animal cells only.\nit is rigid and elastic for supporting the cells shape.\nit prevents harmful substances from entering a cell.
Answer
Brief Explanations:
Cell membrane is a selectively - permeable barrier. It controls the movement of substances in and out of the cell, preventing harmful substances from entering while allowing necessary substances to pass through. Cellulose is in plant cell walls, not cell membranes. Cell membranes are in both animal and plant cells. It is flexible, not rigid and elastic for supporting cell shape (cell walls do that in plants).
Answer:
It prevents harmful substances from entering a cell.
