cell membrane
Transport proteins allow nutrients to enter and leave cells. Transport proteins are peppered throughout the cell membrane. Most molecules need the transport proteins to enter or leave the cell, but it's possible for some molecules, like water, to diffuse through the membrane by osmosis.

Which statements describe the cell membrane? Check all that apply. It only allows certain materials to leave the cell. It allows all materials to leave the cell. It only allows certain materials to enter the cell. It allows all materials to enter the cell. It helps the cell get rid of waste. It brings waste into the cell for storage.
The cell membrane of a plant cell allows certain materials to enter and exit through processes like diffusion, osmosis, and active transport. These processes help maintain the balance of nutrients and waste products within the cell.
Prevents foreign material from entering the cell; and allows nutrients and oxygen to enter while letting metabolites (waste or functional chemicals) out.
Prevents foreign material from entering the cell; and allows nutrients and oxygen to enter while letting metabolites (waste or functional chemicals) out.
The cell membrane is the part of the cell that controls what enters and leaves the cell. It allows nutrients to come in and wastes to move out.
A plant cell membrane lines the inside of the cell wall. The membrane allows only certain molecules into the cell depending on the size. It acts as a filter, and allows food and water to enter the cell, and gets rid of wastes and un-necessary nutrients.
The Plasma membrane.
The cell membrane
The cell membrane separates the cell from its surroundings and controls what can enter and exit the cell through a selective barrier called the lipid bilayer. This barrier allows certain substances, such as nutrients and waste, to pass through while blocking others.
The main function of a cell membrane is to regulate the materials that enter or leave the cell. It ensures that nutrients can enter and wastes can be discarded from the cell.
