Sections of mitochondria in Paramecium and Euplotes present a consistent pattern. The mitochondrion in these cells can be conceived of as a twisted mass of closely compacted tubules. Two general kinds of substances can be recognized: the electron-dense that borders the lumen of the tubule, and the less dense that forms the continuum. In sections of mitochondria in rat kidney and snail oviduct, tubular internal organization can be recognized. In the same organs, mitochondria with lamellar internal structure can be demonstrated. The thesis is developed that the mitochondrion is a structure capable of differentiation and change, and that developmental continuity among the different kinds may exist. Mitochondria that appear to be different may be quite similar basically; mitochondria that appear to be similar in structure may be different in other ways. The tubule is proposed as the most basic of the presently recognized mitochondrial structures.
草履虫和游仆虫中线粒体的切片呈现出一种一致的模式。这些细胞中的线粒体可以被设想为紧密堆积的小管组成的扭曲团块。可以识别出两种一般类型的物质：围绕小管腔的电子致密物质，以及形成连续体的密度较小的物质。在大鼠肾脏和蜗牛输卵管线粒体的切片中，可以识别出管状内部结构。在同一器官中，也可以证明存在具有片状内部结构的线粒体。由此提出的论点是，线粒体是一种能够分化和变化的结构，并且不同种类之间可能存在发育连续性。看似不同的线粒体在本质上可能非常相似；结构上看似相似的线粒体在其他方面可能有所不同。小管被认为是目前公认的线粒体结构中最基本的结构。
