What characteristics are found in the Clade Rhizaria?
similar DNA sequences
thin like pseudopodia
What are the 3 smaller clades included in this larger clade?
Cercozoans, the foraminiferans, and the radiolarians
Where are Rhizaria found?
In marine, freshwater or soil ecosystems
What are the general characteristics for the Clade cercozoans?
Amoeboid shaped Protista with thin pseudopodia
What lifestyle do these cercozoans demonstrate?
They’re predators and parasites found in freshwater, marine, and soil ecosystems
What have cercozoans evolved? How’s it different from plastids?
Evolved a sausage shaped internal structure through endosymbiosis of a Cyanobacteria for photosynthesis which is different from the Cyanobacteria that produced plastids in other organisms
What are the general characteristics for the clade Foraminiferans?
Thin pseudopodia and a calcium carbonate test
Where do foraminiferans live?
Ocean and freshwater habitats attached to rocks, sand, or algae
What do Foraminiferans make up?
sedimentary rock
What are Foraminiferans tests made of? What are the symbiotic with and what do they provide?
They’re symbiotic with photosynthetic algae that can live in their calcium carbonate test and provide them with nourishment
What are the general characteristics for the Clade Radiolarians?
Includes the amoebas with thin pseudopodia and a delicate silica skeleton
Where do Radiolarians live?
Marine plankton
What are Radiolarians tests made of?
Silica
What do Radiolarians form after they die?
Radiolarians ooze
