The cell wall decides what goes in and out of a cell
False! It is the cell membrane that regulates the composition of the cell. In general, cell walls are highly permeable and allow most things to pass through in either direction.
Dialysis tubing is often used to emulate the selective permeability of the cell membrane.
The selective permeability of the cell membrane
The structures within a cell allow it to specialize by allowing each structure to perform a unique or specific function to its adaptation.
It has selective permeability (allows it to control what comes in and out of the cell) and it isolates the cytoplasm.
very complicated question that is better addressed by a cell biology text but in general cell membrane itself is non-polar and allows small non-polar molecules through it also has protein that are built to selectively let in molecule based on commands from the body
Exemples of properties: structure, cell dimensions, lattice energy.
Selective Media - Our cell membrane has a selective permeable property. This type of membranes are important when we want to allow certain sized particles to enter while restricting other sized particles to enter our cell. Selective permeable membrane is of great use in biological samples.
Lipids do give cells membranes a flexible structure that forms a strong barrier between the cell and the cell surroundings. Hence, the lipid surrounds the structure which then forms the shape of the cell.

chloroplasts
The cell membrane allows the passing of some substances.
