heliozoan การใช้

• This heliozoan was also found to carry out rapid axopodial contraction during food uptake at a velocity of about 1 mm / s.
• The actinophryids, " Actinophrys " and " Actinosphaerium ", exist only in a heliozoan form with no flagellum and with more elaborate bundles of microtubules supporting their axopods.
• Unlike other heliozoans, the microtubules are not in any regular geometric array, there does not appear to be a microtubule organizing center, and there is no distinction between the outer and inner cytoplasm.
• Size and shape of the cell body and the scales were examined and compared with other known species of heliozoans, which led us to conclude that this is a new species belonging to the genus Raphidiophrys.
• Others are relatively common in the fossil record, as the diatoms, golden algae, haptophytes ( coccoliths ), silicoflagellates, tintinnids ( ciliates ), dinoflagellates, green algae, red algae, heliozoans, radiolarians, foraminiferans, ebriids and testate amoebae ( euglyphids, arcellaceans ).
• It also appears that certain heliozoa are actually derived pedinellids . " Ciliophrys " alternates between a mobile flagellate stage and a heliozoan feeding stage, where the body is contracted with extended axopods all over its surface, and the flagellum is curled up into a tight figure eight.
• The amoeboflagellates ( e . g ., the rhizarian genus " Cercomonas ", some amoebozoan Archamoebae, some excavate Heterolobosea ) have a peculiar type of flagellate / amoeboid organization, in which cells may present flagella and pseudopods, simultaneously or sequentially, while the helioflagellates ( e . g ., the cercozoan heliomonads / dimorphids, the stramenopile pedinellids and ciliophryids ) have a flagellate / heliozoan organization.
