Screw?
Re: Screw?
Hi,
Xylem cell-wall part....
That's a piece of 'Xylem'secondary-wall thickening, from a plant's water-conducting system. The spiral secondary cell-wall seen here detached from the rest of the cells whence this section came is made primarily of tough (hence their strengthening function to hold-open water conduits) lignin. They often come loose and separate when hand-sectioning plant material.
Nice image, interesting!

Re: Screw?
Thanks for your help and for the biology lesson, I would never have identified it.
Re: Screw?
Most welcome, keep exploring!
You just happened to find a 'bit' in my area - just about anything you find will be of interest here. The kind folk here are able to identify the most amazing variety of critters etc!
Keep enjoying your 'scope my friend.

Hello,
I think it can also be an 'elater' that acts as a spring that projects spores out of the sporophytes of mosses, (mostly) in liverworts.
