The cell membrane is semi-permeable, which means that it allows certain substances to go through.
For substances that are too large, there are vacuoles and transport proteins that assist the large substances.
There is also facilitated transport, passive transport, and active transport. Passive transport is the only one where substances can go through the membrane without the cell expending energy.
The cell membrane, which is a structure surrounding the cell, controls the passage of nutrients, water, and oxygen in and out of the cell. It acts as a selective barrier, allowing specific molecules to pass through via processes like diffusion or active transport.
A cell membrane is in every plant and animal and it lets in water, nutrients, and food to the cell. The membrane MUST be permeable because then it wouldn't of let the in water, nutrients, and food into the cell. If the membrane was stiff, the molecules of water, nutrients, and food would not be able to fit into the cell.
plasma membrane
The cell membrane keeps the cytoplasm inside the cell. It is selectively permeable, allowing nutrients to enter and waste products to exit through various transport mechanisms like diffusion, osmosis, and active transport.
The cell membrane, also known as the plasma membrane, controls what goes in and out of the plant cell. It is a selectively permeable barrier that regulates the passage of nutrients, ions, and waste products.

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.
The function of a cell membrane is to allow certain things in, such as nutrients, ans out such as toxin wastes out of the cell. This allows the cell to get what it needs in order to function. If a cell is functioning properly, then the body is staying homeostasis.
It lets nutrients into the cell, and lets out wastes from it.
The cell membrane of a cell with low mass would be better able to feed all the cytoplasm of the cell. This is because a thinner membrane would allow for more efficient transport of nutrients and waste products in and out of the cell.

The Cell Membrane
The cell membrane, also known as the plasma membrane, is responsible for regulating the flow of nutrients in and out of the cell. It controls the movement of molecules by facilitating selective permeability.
The plasma membrane.
It can allow nutrients to enter a cell without compromising the integrity of the cell. Semipermeable membranes abound in nature.
