Where is Actinosphaerium found?
They are the most common heliozoa in fresh water, and are especially frequent in lakes and rivers, but a few are found in marine and soil habitats as well.
What is the size of Actinosphaerium?
Actinosphaerium species are multinucleate, often reaching a diameter of 1 mm (0.04 inch).
Is a Actinosphaerium autotrophic?
Pseudopods contain coiled microtubules for support, and are sticky so they adhere to prey. Heterotrophic (no chlorophyll).
Is Actinosphaerium prokaryotic?
The Actinosphaerium is a protist (protozoan) and belongs to the Phyllum Sarcodina. It looks like a sea urchin and is from 200-1000 micrometers wide. This is quite large for a protist.
Is Actinosphaerium unicellular or multicellular?
It is a protist that uses its long axopodia to capture prey. Actinosphaeria are also known as sun animalcules and are approximately 0.2 – 1.0mm wide.
Is a Actinosphaerium heterotrophic or autotrophic?
Heterotrophic (no chlorophyll). Prey include flagellates, ciliates other algae, and presumably bacteria.
What is Actinosphaerium adaptation?
The Actinosphaerium has a food vacuole, which is a vacuole with a digestive function in the protoplasm of a protozoan. Also it has an axopod which is a group of thin pseudopods. Next it has an contractile vacuole, which is a vacuole in some protozoans that expels excess liquid on contraction.
