  4. 4. • The needle-like pseudopodia are used to carry out a process called cytoplasmic streaming which is a means of locomotion or distributing nutrients and oxygen. • 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. • Radiolarians are characterized by a glassy silica exterior that displays either bilateral or radial symmetry.

A) Foram shells are made of calcium carbonate, while Radilarians have shells made of silica. B) Foram shells dissolve when the organism dies, while Radiolarian shells sink to the bottom. C) Foram shells have pointy spines,while Radiolarian shells are completely smooth. D) Foram shells exhibit radial symmetry, while Radiolarian shells exhibit bilateral symmetry.
