I think you mean Dialysis. Dialysis filters blood in your kidney for you when you go under kidney work or your kidneys doesn't function like its suppose to. You usually can live off of one kidney, but if your last kidney goes out(Kidney Failure) then they can you up to a dialysis machine and filter your kidneys for you. Hope this helps =]
It allows some molecules to pass through (semipermeable) just like a cell membrane.
Well of course the composition is different and blah blah
They are both semipermeable membranes.
cell membrane
A semi permeable plasmodial membrane
molecular weight higher than the pore size of the tubing or dialysis bag material doesnt go.
Membrane Membrane
A cell membrane can be compared to cloth for several reasons. Firstly, the cell membrane keeps all the organelles, the nucleus and the cytoplasm inside the cell. This is similar to cloth, when you picture a cloth bag. The cloth is strong enough to keep all of the items in the bag. Secondly, a cell membrane can permit small particles of protein, energy and water to the cell. This is similar to cloth because cloth allows things such as water and oxygen to seep through the fabric. Cloth is made of woven thread, and has many small holes, much like the minuscule pores of a membrane. However, a cell membrane is different from a cloth in one specific way. Cloth cannot restrict certain materials from entering, while a cell membrane can. So one could say a cell membrane is like a living cloth, permitting some things to enter the cell and restricting others. A cell membrane can also allow wastes, and carbon dioxide to exit the cell.
a plastic bag or a spounge
Well a tea bag is an example my teacher uses for a cell membrane because there are tiny pores in the cell membrane that allow certain things into and out of the cell. As for the tea bag it allows things in but nothing out, only the tea leaves flavour is let out but not the tea leaves. If your doing a project, play doh or jello works just as fine :D
cell membrane
The cell membrane is on both an animal and plant cell, and a cell wall is a stiff 'box' shape enclosing a plant cell. Think of it as a plastic bag, filled with jelly, with blobs of plastercene in is, the plastercene being the nucleus and the jelly the chlorophill. The plastic bag is a cell membrane. This is an animal cell. Now add a small box and a few more different coloured blobs of plastercene inside the bag- these are the plant cell's vacole and chloroplasts. Put the plastic bag and its contents into a large box- this is a plant cell. The big box is the cell wall.Hope this is useful!

Endocytosis and exocytosis?
Distilled water will move out of the dialysis bag and into the sucrose solution due to osmosis and the fact that the dialysis bag has a hypertonic solution of H2O as compared to the sucrose solution.
