Onion skin

[gekko]

These are a result of my attempt at getting images from onion skin. I also tried iodine tincture staining, but I was not successful. All images were taken with the 20x objective.

1. Cells (oblique illumination):


2. Cells (cross-polarized light):


3. Xylem (bright field):


4. Xylem (cross-polarized light):

Like number 3. Xylem. Works as a record and as a photograph.
I am tempted to have a go.
No microtome, do have a surgical blade though.
Any tips?

Have jumped the gun. See onion. :)

Saw it: beautiful! As to microtomes, I merely peeled by hand a thin "skin" from the onion and then cut a roughly square piece a few mm to the side. No microtomes or surgical blades needed.
