What's the difference between pseudopod and rhizopod?

Pseudopod

Definition:

(n.) Any protoplasmic filament or irregular process projecting from any unicellular organism, or from any animal or plant call.
(n.) A rhizopod.

Example Sentences:

(1) Under conditions of chemotaxis with activated serum beneath the filter, the neutrophil population oriented at the filter surface with nuclei located away from the stimulus, centrioles and associated radial array of microtubules beneath the nuclei, and microfilament-rich pseudopods penetrating the filter pores.
(2) In the latter case, the movement of lectin-receptor complexes occurs from membrane overlying peripheral microtubules into filament-rich pseudopods that exclude microtubules.
(3) The morphology of human leukocytes, the biochemistry of actin polymerization, and the theory of continuum mechanics are used to model the pseudopod protrusion process of leukocytes.
(4) In an activated serum gradient, colchicines, but not lumicolchicine, decreased the orientation of nuclei and centrioles, and caused a decrease in centriole-associated microtubules in concentrations as low as 10(-8) to 10(-7) M. These colchicines effects were associated with the rounding of cells and impairment of pseudopod formation.
(5) In the electron microscope administration of TSH was seen to induce well-known signs of endocytosis, such as formation of pseudopods and colloid droplets.
(6) In addition, some lymphocytes with pseudopods were detected both in alveolar lumen and in the interstitium.
(7) Sections at this region of high membrane turnover reveal a band of densely packed smooth vesicles with round and tubular profiles, some of which are associated with the pseudopod plasma membrane.
(8) The F-actin assembled by 60 sec is localized in these new pseudopods.
(9) The presence of the multivesicular body in the pseudopod or in the vicinity of the pseudopod of the lymphocyte may contribute to the migration.
(10) The ultrastructural studies suggest that the major Tg-induced changes (pseudopod formation and granule centralization) are consistent with a primary role for Tg to mobilize calcium; DPPE had very little effect on these ultrastructural changes.
(11) The secretion of thyroid hormones under the influence of pituitary thyrotrophin (TSH) from stores in the luminal colloid is initiated by elongation of microvilli and formation of pseudopods.
(12) The second stage of actin assembly, which peaks at 60 sec following an upshift in cAMP concentration, is temporally correlated with the growth of new pseudopods.
(13) (8) The development of platelet constriction, platelet pseudopods and the intracellular microfilaments are delayed in colchicinized clots, corresponding to the retardation of retraction.
(14) Bound CGP-ABY was cleared first from the tips of the projections and subsequently from the entire pseudopod surface.
(15) The actin-binding protein ABP-120 has been proposed to play a role in cross-linking F-actin filaments during pseudopod formation in motile Dictyostelium amebas.
(16) The formation of pseudopods is impaired and no microtubules are found in platelets in the presence of colchicine.
(17) When motility was compared between sublines, membrane ruffling and cellular translation were relatively unaffected by substrate, whereas pseudopodal extension was altered significantly by different substrates.
(18) After correcting for effects of pseudopods and platelet size on platelet diffusion and sedimentation, it still appeared that the small number of long pseudopods formed on human platelets could largely explain the unusually large alpha B values.
(19) No such changes were observed in non-sensitized M. In contrast, when immunosuppressants or immunomodulators were used, increases of pseudopod movement and pinocytosis, and excitation of cytoplasmic movement, were observed in both sensitized and non-sensitized M if compounds were cytotoxic.
(20) From the enlarged apical plasma membrane, pseudopods are formed.
