Leaf soaked in hot water

In Systems Workbook Activity 2.4 (page 15), we recalled that there are tiny openings found on the surfaces of the leaves.

Let's soak a leaf in a container of hot water and observe.


Observations:
  • There were many tiny bubbles on the leaf. 
  • There were more bubbles on the lower surface than on the upper surface.
