HELIOZOA definition - English
URL: http://www.books.md/H/dic/Heliozoa.php

Order Heliozoida. A group of amoeboid protozoa. They are generally free floating, spherical cells with many straight, slender microtubule supported pseudopods radiating from the cell body like a sunburst. These modified pseudopods are termed axopodia. Genera include Actinophrys and Echinosphaerium.

Heliozoa exhibit a sphaerical cell-body containing one or more nuclei. Along the axopods, mitochondria, vesicles and other particles may be transported underneath the plasma membrane in a process called "granular streaming". Often, an apparently looser ectoplasm with pulsatile vacuoles can be distinguished from a denser endoplasm with nuclei. Mostly asexual propagation, sexual propagation known only from Actinophrys and Actinosphaerium.

The heliozoa are radially symmetrical unicells characterised by the possession of long, slender cytoplasmic arms called axopodia, stiffened by a complex structure of microtubules. Cytoplasm flows continuously back and forth along the axopodia, conveying bacteria and anything else which adheres to them back to the cell body. Larger prey such as algal cells may become enmeshed in the axopodia and similarly incorporated into the cell body.

Sonnentierchen, Heliozoa - German

Zur Ordnung der Heliozoa oder Sonnentierchen zдhlt das ca. 250 µm groЯe Strahlenblдttchen. Die zahlreichen Strahlen werden Axopodien genannt. Sie sind feine, offensichtlich giftige Plasmafortsдtze, die durch eine gelartig verfestigte Plasmaachse verstдrkt werden. Vorbeischwimmende Wimper- oder Rдdertiere werden gelдhmt oder vergiftet und anschlieЯend von den Pseudopodien, das sind bewegliche, kontrahierfдhige ScheinfьЯchen, ins Innere gezogen und verdaut.
