Which of the following is a role of the cell membrane?

Together, let's examine and evaluate the available options.

A. Generating nutrients for cells

That's not the answer; I'm pretty sure that the Golgi apparatus, nucleus, and endoplasmic reticulum are the only parts of the cell that produce nutrients (like proteins, lipids, carbohydrates, etc.).

B. Holding onto cellular wastes

This isn't the solution because the cell's lysosomes are filled with enzymes that are specifically designed to remove waste from the cell; think of them as a collection of trash cans.

C. Chemicals that neutralize

Since the cell membrane is not involved in the process of preventing too much acidity or alkalinity from damaging enzymes and proteins, I would say that this is not one of the answers.

D. Preserving equilibrium

An organism's natural tendency to maintain a stable state is known as homeostasis. This is due to the fact that the cell membrane permits certain ions and molecules to pass through while blocking others, and this process is necessary for the cell to remain healthy. Additionally, the cell undergoes frequent osmosis because it needs water, and active transport occurs because the cell needs other ions, like nitrates, to make proteins.

The plasma membrane is responsible for maintaining homeostasis (Sciencing, 2019).

This is the right response, in my opinion, since the majority of the process involves the cell membrane. If you are still unsure, consult your teacher or instructor as usual.

Controlling the flow of chemicals into and out of cells is one function of the cell membrane.
