How does the cell membrane protect the cell?

Answer 1

A cell membrane protects a cell by controlling what substances go in and out of the cell. It lets good products go inside, but harmful products go out, which is basically protecting the cell.

Think about a cell membrane as Immigration or border patrol. Border patrol or immigration protects a city and allows good people to come in, and bad people to go out, just like a cell membrane.

Answer 2

It acts like a skin or barrier to keep harmful materials outside the cell, plus keep imortant things inside. It works by being semi-permeable, which means having small openings that allow certain things in and out, like water and small molecules, like simple sugars, while keeping larger molecules out.

Answer 3

The cell membrane acts as a barrier, controlling the entry and exit of substances in and out of the cell. It also helps maintain internal conditions necessary for the cell's survival and protects the cell's organelles from potentially harmful molecules. Additionally, the cell membrane has receptor proteins that can initiate responses to signals from the cell's environment, enabling the cell to adapt and respond to changes.

Answer 4

it controls what goes in and out of the cell.
