High resolution image of typical cytoplasm of Coleps hirtus. The cytosol contains rough ER, mitochondria with tubular cristae, peroxisomes, early endosomes, and bacterial endosymbionts. Small and large extrusomes are also present. The bacteria are contained in vacuoles bearing ribosomes on their cytosolic side. Elements of the outer cortex: alveoli, plasma membrane, inner alveolar membrane, outer alveolar membrane are evident as well as the Golgi complex. Standard glutaraldehyde fixation followed by osmium tetroxide, dehydrated in alcohol and embedded in an epoxy resin. Microtome sections prepared at approximately 75nm thickness. TEM taken on 5/23/69 by R. Allen with Philips 300 operating at 60kV. Neg. 14,800X. The raw film was scanned with a Nikon Coolscan 9000ED. This high resolution image is suitable for quantitative analysis Additional information available at (http://www5.pbrc.hawaii.edu/allen/).
