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.

Which part of an animal cell lets food water and oxygen pass in and out?
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.
What structures allow large important molecules to pass through the cell membrane?
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.
What is the bacterial structure that acts as a selective barrier allowing nutrients to enter the cell and wastes to leave the cell.?
plasma membrane
What keeps the cytoplasm inside and allows nutrients in and waste products out?
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.
A membrane at the boundry of every cell that acts as a selective barrier?
The cell membrane is a phospholipid bilayer that acts as a selective barrier, controlling the passage of molecules into and out of the cell. It helps maintain cellular homeostasis by regulating the entry and exit of substances such as ions, nutrients, and waste products.
How does a does a cell get water and nutrients?

Which part of a cell allows nutrients and other materials to enter or leave the cell?
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.
What does homeostasis have to do with with the cell membrane?
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.
Cell membrane what does a cell membrane to in a plant?
It lets nutrients into the cell, and lets out wastes from it.
Which is better able to feed all of the cytoplasm of the cell the cell membrane of a cell that has high mass or the cell membrane of the cell that has low mass?
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.
What allows nutrients to enter the cell?
cell membrane
What part of a cell makes nutrients?
The Cell Membrane
Which cell organelle regulates the flow of nutrients in and out of the cell?
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.
How does nutrients enter a cell?
The plasma membrane.
How does the movement of materials across the cell membrane relate to an organism's survival-?
It can allow nutrients to enter a cell without compromising the integrity of the cell. Semipermeable membranes abound in nature.
Which cell part that controls the passage of nutrients into the cell?
the cell membrane
Which part of an animal cell lets food water and oxygen pass in and out?
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.
