The cross-section of the malpighian tubules often shows 2 or 3 relatively large epithelial cells, resting on a thin basement membrane. Basal, intermediate and apical zones of each cell exhibit a characteristic structural appearance. The basal zone, where many mitochondria and vacuoles are located, is characterized by infoldings of the cell membrane, namely, a basal striation. The intermediate zone contains a number of vacuoles of varying sizes, and lime granules are 0.1 to 3 microns in diameter. Each of these granules is constructed of 2 to 7 layers. In addition, many mitochondria and coarse endoplasmic reticulum are seen near the apical zone. Clods of electron-dense granules, about 400Å in diameter, are scattered in the basal and intermediate zones. In the apical zone which forms the brush border, a multitude of vertically arranged protoplasmic processes are seen. Each process contains a mitochondrion whose cristae run mostly parallel to the process.
