Do you mean how do substances move through a cell membrane if they are too big to transport by passive transport?
If so, a cell uses active transport to move large particles in and out of a cell. Active transport includes endocytosis, pinocytosis, and phagocytosis.

How does the composition of the cell membrane help regulate the movement of substances into and out of the cell?
They pass through channels in the cell membrane.
What only allows certain substances in and out of a cell?
The permeability of the cell membrane controls which substances may pass in or out of the cell.
The neuron's cell membrane permits some substances to pass through but not others this is because the membrane is?
One of the characteristics of a cell membrane is that it is semi-permeable. As such, it is able to limit what can get into and out of the cell.
What single characteristic of the semipermeable membrane used in the laboratory determines the substances that can pass through them?
The size of the membrane pores determines which molecules can pass through.
State one possible reason a certain substance can not pass across a cell membrane?
The cell membrane is selectively permeable. Some substances like molecules are too big to pass through the membrane. The membrane allows passive transport of moleculesÊ by filtration, diffusion, or osmosis.
How does the composition of the cell membrane help regulate the movement of substances into and out of the cell?
They pass through channels in the cell membrane.
What specific substances can pass through a cell membrane by diffusion?
Oxygen
What property in the cell membrane that allows only some substances in?
Semi-permeable. Permeable means things can pass through, so semi-permeable means only some things can pass through.
Which part of a cell allows substances to pass through it?
The cell membrane, which encloses the cell, is a selective membrane which allows some molecules to pass and others not.
What is the cell membrane which means that some substances can pass through it while others can't?
Semipermeable membrane.
What only allows certain substances in and out of a cell?
The permeability of the cell membrane controls which substances may pass in or out of the cell.
What does the cell membrane do to avoid hings going inside the cell?
Cell membrane is a Selectively Permeable Membrane so it does not allow all the substances to pass through it.It controls the movement of substances in and out of the substances.Unlike a cell membrane,the cell wall has large holes in it allowing the water and dissolved minerals to pass through hence cell wall is known as Freely Permeable Membrane.
What must a substance pass through to enter or leave a cell?
If substances did not pass through cell membranes, then all single-celled and multicellular organisms would die.
What characteristics of cell membrane allows for some substances to pass through but not others?
wwww
Through which organelle do substances enter or leave a cell?
Substances pass through the plasma membrane, although ot is not technically an organelle.
Can the lipid pass through the cell membrane?
yes. Lipid soluble substances are highly permeable
What substances must pass through a cells's membrane for the cell to continue to function?
water and nutrients.
