The procedure to perform a cell membrane experiment is to:
- Use beetroots cells to measure the permeability of the membrane
- This is done to check the content of the pigment
- It is also meant to check the pigment leaks out of the cells.
<h3>What is a Cell Membrane?</h3>
This refers to the semi-permeable membrane that is around the cytoplasm of a cell.
Hence, we can see that the main purpose of the cell membrane practical experiment is to test the permeability of a membrane and to see the amount of liquid that a membrane can hold.
Please note that your question is incomplete so I gave you a general overview to get a better understanding of the concept.
