Experiment No. 10:
Observing leaf cells
Objects: A fresh leaf, clean and dry, without holes
or blemishes
With an adult's supervision, cut a one-inch cross section
out of the center of the leaf, from one side of the leaf to
the other. Tightly roll that section up starting from one uncut
edge of the leaf. The central vein of the leaf will be in the
center of the roll and not be visible. Then make several
very thin slices off one end of the roll. The central vein will
be in the middle of this almost transparent slice. You'll be
observing the cells around that central vein. Using a droplet
of water, make a wet mount (as in Experiments 8 and 9),
placing the leaf segment so that the inner part faces up.
Start with the lowest power and gradually increase the
magnification for more detail.
