Answer:

The cell membrane has two functions: first is to keep the constituents of the cell in and unwanted substances out. Its second function is to be a gate allowing the transport of essential nutrients into the cell and movement from the cell of waste products. It's important because it protects the cell.

Answer:

The cell membrane is a multifaceted membrane that envelopes a cell's cytoplasm. It protects the integrity of the cell along with supporting the cell and helping to maintain the cell's shape. Proteins and lipids are the major components of the cell membrane.
