Pleurotaenium - Desmid

Post by NikonUser »

For a full image of a specimen in this genus, possibly same species, see
HERE

Pleurotonium is common in my samples and is readily recognizable due to its habit of attaching itself to the substrate at the polar end of one semicell with the rest of the desmid projecting vertically.
Each polar end is perforated by minute pores which I believe secretes the ‘glue’.
Photo shows one polar end and the pores. I measured these pores as having a diameter of 0.6µ and they show only in single frames (thus stacking is not an option) even though frames were taken at about 0.7µ spacings.

Quote – Holmes on ‘Entomology’
” I suppose you are an entomologist ? “
” Not quite so ambitious as that, sir. I should like to put my eyes on the individual entitled to that name.
No man can be truly called an entomologist,
sir; the subject is too vast for any single human intelligence to grasp.”
Oliver Wendell Holmes, Sr
