In the lab experiment, the semipermeable membrane you will use is dialysis tubing, shown above with a solution inside. Which part of a cell is the dialysis tubing most similar to? cell wallnucleuscytoplasmcell membrane

Dialysis tubing is semipermeable: it allows some substances to pass through while restricting others. The cell structure with this same selective-barrier role is the cell membrane, so the correct choice is cell membrane. The cell wall mainly provides support and protection, while the nucleus and cytoplasm do not form the cell’s outer selective barrier.
