SYNOPSIS. About 50% of the amoebae found in early prophase through metaphase stages of mitosis have at least some mitochondria (ca. 25%) that contain complex internal structural patterns. These patterns are less frequently seen in mitochondria after metaphase, and they are extremely rare or absent during interphase. In the most typical pattern, larger than normal tubules are arranged in a parallel zig‐zag configuration with a small amount of matrix between them. Complex patterns typically comprise about 30% of the mitochondrion; they are usually confined to one area, the remaining portion consisting of a clear matrix with few, if any, peripheral tubules.
