Image of the 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. Bar = 0.5µm. A print of the negative was scanned and processed in Photoshop. This image is best used for qualitative analysis. A high resolution image (CIL:2881) is available for quantitative analysis. Additional information available at (http://www5.pbrc.hawaii.edu/allen/).
