Three Years in Micrographs

August 11, 2016

For the past three years as a biology student, I spent every Tuesday and/or Thursday in the coldest labs for three hours or so. Some of them pass by more easily than others, but I always love one with some microscopy involved. I started taking photos through the microscope in freshman year out of curiosity and laziness (surprise!) so my teary eyes wouldn’t have to strain so much to sketch these. I thought I’d share the best in my collection so far as I enter my senior year! If any of you are interested in my methods to take these photos, I just used my iPhone with a really steady hand to the eyepiece.

The classic onion root tip stain freezing some cells in the late stages of cell division.
A hydra greedily nabbing three Daphnia water fleas with its stinging arms.
Onion skin stained with methylene blue.
Potato cells stained with iodine. Vesicles full of starch turn black instantly once the iodine hits.
A chain of some unknown streptobacillus bacteria.
Stained pine stem.
Onion root mitosis, this time frozen in anaphase.
I believe this is the cross section of a frog cilia, but it’s been four years and I probably remembered incorrectly.
Human bone cells, osteons.
Epithelial cheek cells, stained, prepared, donated by yours truly.
Pith and xylem of a dicot plant stem.
