Experimental evidence shows that organic carbon fixed by algae is assimilated by the radiolarian host. Fascinating schemes have been observed in which the symbionts spread far out in pseudopodial networks during daylight and are retracted at night.

Radiolaria can range anywhere from 30 microns to 2 mm in diameter. Their skeletons tend to have arm-like extensions that resemble spikes, which are used both to increase surface area for buoyancy and to capture prey. ... Radiolarian Database, Nagoya University...

When Radiolarians die, their glass shells sink to the bottom of the ocean into what's called the radiolarian ooze. This gunk is what eventually forms sedimentary rock.

It is thought that the evolution of diatoms in the Cretaceous may have had a significant effect on radiolarian evolution due to competition for silica (diatoms also use silica to build their skeleton); it is commonly accepted that radiolarian skeletons have become finer and less robust from this time.
