PELOMYXA CAROLINENSIS (WILSON) OR CHAOS CHAOS (LINNAEUS)?

Mitochondria I. Fine Structure of the Complex Patterns in the Mitochondria of Pelomyxa carolinensis Wilson (Chaos chaos

Some of the mitochondria in the free-living giant ameba Pelomyxa carolinensis (Chaos chaos) exhibit unusual and strikingly complex morphological patterns. A study of serial sections of these mitochondria reveals that the patterns are formed by the organization and packing of minute villi (cristae mitochondrlales). The form of the individual villus is a regular soft zigzag (or wave) with a bulbo...

Microfilaments in Chaos Carolinensis

Recent ultrastructural studies indicate that 50-70 A microfilaments are found in a variety of cell types (1, 10, 25, 27), some of which exhibit shape changes (6, 26), cell motility (4, 5, 17, 18), and cytoplasmic streaming (2, 3, 28) . Biochemical investigators have isolated and purified an actinlike protein from Physarum polycephalum (2, 29-33), the amoebae of Dictyostelium discoideum (34), an...

Chaos vs. Order: Aristotle and Linnaeus

Contractile vacuole in the amoeba Pelomyxa carolinensis.

RIDDICK, DANIEL H. Contractile vacuole in the amoeba, Pelomyxa carolinensis. Am. J. Physiol. 215(3): 736-740. 1968.-The osmolality of the cytoplasm and contractile vacuole of the giant amoeba Chaos chaos was determined by micropuncture. Sodium and potassium concentrations of the cytoplasm and contractile vacuole were similarly obtained. Single contractile vacuoles were isolated. It was determin...
