Description

High resolution image of Colpoda. A soil ciliate and this micrograph is characterized by numerous mucocysts and food vacuoles containing bacteria in various stages of digestion. This electron micrograph is near the posterior end of the cell and contains spongiome tubules of the contractile vacuole. Rows of cilia cover the cell and basal body/cilium complexes are present as dikinetids, two complexes in each cortical unit. TEM taken on 5/31/69 by R. Allen with Philips 300 operating at 60kV. Neg. 5,000X. The raw film was scanned with an Epson Perfection V750 Pro. This high resolution image is suitable for quantitative analysis.
