Abstract 1. 1. Paramecium caudatum contains a multiple form of hemoglobin (Hb), which is composed of high concentration of a major variant and only a small amount of several minor variants. 2. 2. The electrophoretic mobility and molecular weight of the major variant in P.

The Endosymbionts of Paramecium
CRC Critical Reviews in Microbiology, 1974AbstractProtozoan cells harbor many different types of endosymbionts. They can be viruses, bacteria, algae, fungi, or even defy classification in relation to free-living organisms. A general description of the types is available in Kirby1 and some are shown in Table 1.

THE ciliated protozoan Paramecium provides an opportunity to study the electrophysiological properties of an excitable membrane in relation with simple locomotor behaviour. The Paramecium surface membrane controls the locomotor activity, in particular ciliary reversal (resulting in backward swimming), by ionic conductance mechanisms like those in other

Imagine that in 1678 you are Christiaan Huygens or Antonie van Leeuwenhoek seeing paramecia swim gracefully across the field of view of your new microscope. These unicellular, free-living, and swimming cells might have remained a curiosity if not for the ability of H.S. Jennings (Behavior of the lower organisms.

Mitochondrial Genetics in Paramecium
Nature, 1972RESISTANCE to erythromycin and chloramphenicol in yeast has been shown to be controlled by non-Mendelian genetic factors in mitochondrial DNA1,2. Because paramecium has particular advantages for the study of cytoplasmic genetics3, we have made some genetic and biochemical studies on drug-resistant variants of this ciliate, working with syngens 1 and 4 ...

The Cell Surface of Paramecium
1959Publisher Summary This chapter provides a general description of the structure of the cell surface of Paramecium . The trichocysts, at their tips, are homologous with cilia. If the ciliary corpuscles composing the cell surface are like a layer of packed peas, then the trichocysts underlying the surface in orderly array are somewhat like a second ...

A theory of gravikinesis in Paramecium
Advances in Space Research, 1996The archaic eukaryote unicellular microorganism, Paramecium, is propelled by thousands of cilia, which are regulated by modulation of the membrane potential. Ciliates can successfully cope with gravity, which is the phylogenetically oldest stimulus for living things.

[Motor activity of paramecium].
Biofizika, 2000A systemic study of the mechanisms of motor activity of paramecium was carried out. The movements of paramecium responding to various influences were photographed. The analysis of the data revealed the time dependences of the rate of movement, rate of rotation, and the radius and the pitch of the helix trajectory.

Aquatic organisms have the capability of detecting and responding to chemical stimuli. The stimulus can signify the presence of food, mates, predators, or a place to settle and continue development. Unicellular aquatic organisms are not exceptions and as an example, I discuss chemoresponses of Paramecium tetraurelia, a ciliated eukaryotic microorganism.
