How to cut a leaf blade for a biology experiment

Place the leaf blade flat on a small wooden board (a slide will do), pinch the two blades side by side, and quickly cut along the surface of the leaf in a direction perpendicular to the veins. Cut several times. Keep the thin slices in the crevices of the blades, put them in water, and stick the thinnest one with a brush to make a temporary slice specimen.

If the answer is as described above. If you do your own experiments and need good phenomena, my experience is:

1 Leaf selection is important. I think that the common spinach, after soaking in water for half an hour, works well.

2Blades should be sharp, preferably new. Sometimes rusty, the effect is not good.

3 The lower surface of the blade is placed facing upwards, which is good for getting a good specimen.

4 In my opinion, the textbook says to cut quickly, it does not work well, the structure of the cross section of the leaf is damaged and not neat when seen under the microscope. When I did this experiment, I had the blade perpendicular to the leaf, pinched the blade tightly with my right and left thumbs and forefingers, and quickly dropped and cut vertically like chopping vegetables. The effect is good.
