The plasma membrane proteins of a cell can be linked to colored marker molecules. In an experiment, you labeled the membrane proteins of one cell with a red marker and the membrane proteins of a second cell with a blue marker. Using your understanding of
the fluid-mosaic model, what might you see happen if you connected the plasma membranes of the two cells so that they form one continuous membrane?
What will be an ideal response?
The plasma membrane is fluid, so the proteins are free to move across the membrane. Eventually, the red proteins of one cell would move to the membrane of the second cell, and the blue proteins of the second cell would move to the membrane of the first cell. Eventually you would have an even mix of red and blue proteins throughout the membrane.
