1.	Question : Mount the peel of a Rheo leaf in water on a slide and examine cells under the high power of a microscope. Put a strong solution of sugar or salt on the mounted leaf on the slide. Wait for a minute and observe under a microscope. What do we see?
Answer» Solution :The green coloured chloroplasts are seen in the mounting. Due to strong SUGAR or salt solution on the outer side of the CELL, the water moves out due to concentration difference. Exosmosis takes place and this causes cells to shrink. SHRINKAGE of the contents of the cell AWAY from the cell WALL is called plasmolysis. In this activity plasmolysis can be observed. Now place some Rheo leaves in boiling water for a few minutes. This kills the cells. Then mount one leaf on a slide and observe it under a microscope. Put a strong solution of sugar or salt on the mounted leaf on the slide. Watt for a minute and observe it again.
