چکیده

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 determined that the vacuole grows in size while maintaining a constant hypotonicity of its fluid relative to the cytoplasm. An hypothesis of the formation and function of the contractile vacuole is put forth.

The Fine Structure of the Contractile Vacuole in Ameba

The contractile vacuole is an organelle found in most freshwater Protozoa. In ameba, as studied with the light microscope, it is usually described as spherical, with a rather thick limiting membrane and surrounded by a layer of mitochondria (Fig. 1). The contractile vacuole undergoes a continuous series of cyclic changes. I t enlarges gradually (diastole), collecting water until it reaches a cr...

Regulation of cellular osmolarity and volume in Tetrahymena.

Freshwater Protozoa are hyperosmotic to their environment. Direct determinations of intracellular osmolarity on Amoeba proteus and Pelomyxa carolinensis have given values between 101 and 117 m-osmole/kg cells, when the external osmolarity was 2-8 m-osmole/1 (Lovtrup & Pigon, 1951; Riddick, 1968; Schmidt-Nielsen & Schrauger, 1963). No measurements were made of intracellular osmolarity in respons...

Electron Microscopy of Mitosis in a Radiosensitive Giant Amoeba

Various aspects of the ultrastructure of the dividing nuclei in the large radiosensitive amoeba Pelomyxa illinoisensis are demonstrated. Evidence of nuclear envelope breakdown is presented, and membrane fragments are traced throughout metaphase to envelope reconstruction in anaphase and telophase. Annuli in the nuclear envelope and its fragments are shown throughout mitosis. During metaphase an...

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...
