Dialysis tubing is often used to model a cell membrane because it is also a semi-permeable membrane. This means that it only allows certain substances through, not all.

∙ 10y agoBecause it resembles the cell membrane in that the pores are small enough for the solute to not go through without some other substance.

What cellular structure is the dialysis tubing representing in this lab?
The cell membrane :]
Is unit model and Robertson's model of cell membrane alike?
the unit membrane model is robertson's model of the plasma membrane (cell membrane)
How does a visking tubing differ from a cellmembrane?
Visking tubing contains millions of tiny holes which only let small molecules, like water, diffuse through. Large molecules, such as starch, cannot cross the membrane. We say it is partially permeable (permeable means a substance is able to pass through). This is similar to a cell membrane. Visking tubing can therefore be used as a model of a cell.
The outside of an animal cell is?
This is the cell membrane or plasma membrane which is made of a phospholipid bilayer.
What is described by the fluid mosaic model?
The cell membrane.
What cell structure the dialysis tubing represents?
Dialysis tubing is often used to emulate the selective permeability of the cell membrane.
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.
A cell membrane is like a what?
A semi-permeable membrane. It could be compared to dialysis tubing.
What cellular structure is the dialysis tubing representing in this lab?
The cell membrane :]
What does dialysis tubing represent in your model?
Dialysis Tubing is a type of semi or partially permeable membrane tubing made from regenerated cellulose or cellophane. It is used for diffusion, or more accurately osmosis. It allows the passage of small molecules but not larger ones. It is used in clinical circumstances to ensure a filtered flow of molecules, preventing the flow of larger solute molecules. Small molecules can be 'washed' out of a solution which is pumped through the tubing into a solvent, usually water, which surrounds it and in which they can be flushed away.
What cell structure can the dialysis sac be compared to?
The cell membrane
What biological structure is the dialysis bag comparable to?
cell membrane
Is unit model and Robertson's model of cell membrane alike?
the unit membrane model is robertson's model of the plasma membrane (cell membrane)
Components of the cell membrane constantly shift. The model describes this characteristic of the cell membrane.?
Yes, the Fluid Mosaic Model of the cell membrane describes this characteristic.

Why can starch molecules not pass through dialysis tubing?
It is a complicated molecule. the starch molecule is to large to be transported through the cell membrane. it therefore has to be broken down if it is to go though the protein channels.
What substance crossed the dialysis membrane?
Cells have methods other than diffusion/osmosis to move materials across the cell membrane, most of which involve membrane proteins and require the use of energy. The cell membrane also performs functions other than controlling the movement of materials into and out of the cell, and the membranes of some specialized cells have very complex functions. So we can see that the cell membrane is a very intricate and important component of the cell.
