heliozoa การใช้

• In the past, nucleariids were included among the heliozoa as the Rotosphaerida.
• In 2010, Thomas Cavalier-Smith indicated his desire to move Alveolata, Rhizaria and Heliozoa into Chromista.
• Some of this organization is found among the heliozoa, but those lack central capsules and only produce simple scales and spines.
• He chose the lab of Max Hartmann, a protozoologist, to study the reproduction of a protozoan of the order Heliozoa.
• This was questioned when it was found they have mitochondria with tubular cristae, as do other heliozoa, while in centrohelids the cristae are flat.
• "' Heliozoa "', commonly known as sun-animalcules, are microbial eukaryotes ( protists ) with stiff arms ( marine environments.
• The Chromista ( Cavalier-Smith, 2010 ) included Harosa ( Stramenopiles, Alveolata and Rhizaria ) and Hacrobia ( Haptophyta, Cryptophyta and centrohelid Heliozoa ).
• Other heliozoa where the microtubules arise from the nucleus have been considered possible relatives, and it now appears that the actinophryids developed from axodines such as " Pedinella ".
• These include the radiolaria and heliozoa, which produce axopodia used in flotation or to capture prey, and the haptophytes, which have a peculiar flagellum-like organelle called the haptonema.
• For instance the centrohelids are often placed in a polyphyletic class Heliozoa, but this group also includes the actinophryids which have a known phylogenetic placement elsewhere, so it is better not to use it as a formal taxon ( just a phenotypic group ).
• 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.
