What is the part of the cell that materials pass through?

Materials pass through the cell membrane, which acts as a barrier between the cell's interior and the external environment. The cell membrane is selectively permeable, allowing certain substances to pass through while blocking others.

No they pass through the cell membrane. The cell membrane is selectively permeable to ions and organic molecules


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 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.


Why is it important for the cell membrane to be fluid?

The reason why the cell membrane requires a fluid consistency is to allow certain molecules to pass through. Fluidity is also important for phagocytosis to take place.


What is dialysis tubing supposed to mimic?

The dialysis tubing is meant to represent the semi permeable membrane of a cell. Like the cell membrane, dialysis tubing has holes or pores that only allow certain things to pass through. A cell membrane similarly will only allow certain things to pass in and out.


What part of the cell membrane allows small molecules to pass through?

What is the semipermeable membrane?

The cytoplasm of a cell is surrounded by a cell membrane or plasma membrane. The membrane is said to be 'semi-permeable', in that it can either let a substance pass through freely, pass through to a limited extent or not pass through at all.the membrane is somewhat effective at letting fluids through
