Are Rhizaria Unicellular or Multicellular?

The Rhizaria are a species-rich supergroup of mostly unicellular eukaryotes. Except for the Chlorarachniophytes and three species in the genus Paulinella in the phylum Cercozoa, they are all non-photosynthethic, but many foraminifera and radiolaria

Is Rhizaria multicellular?

The Rhizaria are a supergroup of mostly unicellular eukaryotes. A multicellular form has recently been described. This supergroup was proposed by Cavalier-Smith in 2002. It has many species.

Are Rhizaria autotrophic or heterotrophic?

Two major subclassifications of Rhizaria include Forams and Radiolarians. Forams are characterized as unicellular heterotrophic protists that have porous shells, referred to as tests, which can contain photosynthetic algae that the foram can use as a nutrient source.
