What cellular structure is the dialysis tubing representing in this lab?
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 cell structure can the dialysis sac be compared to?
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 biological structure is the dialysis bag comparable to?
cell membrane
Why do you use dialysis tubing as a model for a cell membrane?
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.
Does the largest circular structure represent a host cell?
it represents the nucleus
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.
The diagram represents a white blood cell engulfing bacteriathe structure label x is most likely a?
vacuole
What is dialysis sac of a living cell?
what are living cells
