Just use tweezers to tear off the skin of the onion. The cut will be too thick. If you want to cut it, use two thin blades to hold it together, cut it off, and then dip it in water. The thin onion slices will float on the water~

Another important point for mounting slides is that there must be no bubbles in your slides~~

Put an onion slice on the slide Thin slice, add a drop of water, and then carefully cover it with a coverslip~

Try to avoid air bubbles~

Basically, these two points should be paid attention to. The rest of the methods should be in the textbook~~Other than that, they are all microscope operations~

If I haven’t missed anything, that’s it~

I studied biology in high school.

I hope you can pass~
