Question

1. Few dried apricots are placed in beaker ‘A’ and beaker ‘B’ for some time. It is found that they shrank in beaker ‘A’ and became swollen in beaker ‘B’. What conclusions can you draw regarding the nature of liquids in beakers ‘A’ and ‘B’? Give justification.

Answer 1

1. The beaker ‘A’ should contain a higher concentrated solution (hypertonic solution) and hence, exosmosis takes place. During exosmosis, the water inside the cell will move out to the surrounding solution. Due to this, the apricots shrink.
2. The beaker ‘B’ should contain a lower concentrated solution or water (hypotonic solution) and endosmosis takes place. During endosmosis, the water molecules from the surrounding solution will move into the cell. Due to this, the apricots become swollen.
