I know with 4%, it is hypertonic and plasmolysis occurs (so cell shrinks (?)). With 0.4%, it is hypotonic and the cell ____(shrinks/expands)? 4M causes the cell to expand and plasmolysis also occurs.
But what about 0.4M NaCl being added to the elodea cell? Is it hypotonic or hypertonic? And what shape changes occur? It's got me stumped.
Thanks!
