Diatoms from diatomaceous earth bought to control red mite on poultry.
This is a tungsten filament from a 40w ses lightbulb. The red background is simply electrical tape on the underside of the slide, for contrast.
One of several diamonds in my wife’s eternity ring. I really wanted to do a bright field illumination shot but had to use reflected light. The rear of the diamond was too enclosed for transmitted light.
I was disappointed there wasn’t much more interesting shape to these but I suppose they are just clumps of powder at the end of the day.
Ok, so when I first saw these my initial thought was that these might be stomata, which are ports/pores allowing gasses in and out of a leaf or stem. The two halves of the roughly round shapes are cells, called guard cells and they control the opening and closing of the pore.
They are surrounded by some organic material, possibly leaf debri which falls into my pond from various plants, including Ivy.
If anyone can identify what these are, please let me know. The whole area which included these was only a few millimetres square, barely visible to the naked eye. I think this was taken using a 40x objective, so will be either x400 or x800 magnification, probably the latter.
I might find some whole leaves from the pond and see if I can find something as a basis for comparison, then I may even be able to tell exactly which type of plant this tiny piece of debris came from.
This little fella is about 3mm long. The hairs between segments in the last photo are therefore probably only 50 microns long. You can even see something impaled on the hairs to the left.
Have just ordered some stains, reagent and mountant so should be uploading some interesting botanical subject photos soon!
