Is foraminifera unicellular or multicellular?
Foraminifera (forams for short) are single-celled organisms (protists) with shells or tests (a technical term for internal shells). They are abundant as fossils for the last 540 million years.
Are foraminifera phytoplankton or zooplankton?
About 40 of the 4,000 currently living species of foraminifera are considered to be plankton. Specifically, foraminifera are classified as zooplankton …
What are radiolarians shells made of?
Radiolarian shells Radiolarians are unicellular predatory protists encased in elaborate globular shells usually made of silica and pierced with holes.
Are radiolarians heterotrophic or autotrophic?
Fusules are unique to Radiolaria and their close relatives the Acantharia. Because Radiolaria are heterotrophic they are not limited to the photic zone and have been found at water depths as great as 4000m.
Is radiolarians zooplankton or phytoplankton?
Radiolarians are zooplankton. They are also protozoans, which are single-celled organisms with a membrane-bound nucleus.
What are radiolarians known for?
radiolarian, any protozoan of the class Polycystinea (superclass Actinopoda), found in the upper layers of all oceans. Radiolarians, which are mostly spherically symmetrical, are known for their complex and beautifully sculptured, though minute, skeletons, referred to as tests.
What is the phylum Sarcodina?
The Phylum Sarcodina is comprised of protozoan, or sarcodines, that share several characteristics; sarcodines have long, trailing cytoplasm and use unique cytoplasmic feet, or extensions, called pseudopodia to facilitate movement.
What are the characteristics of Sarcodina?
Sarcodina is a superclass of the phylum Protozoa, members of which are known as Sarcodine. These have streaming cytoplasm and use pseudopodia in locomotion and feeding.
What are the three classes of Sarcomastigophora?
The subphylum Sarcomastigophora is further classified into three classes, Sarcodina, Mastigophora and, Opalinata. The class Sarcodina is then further classified into subclasses of Rhizopoda and Actinopoda.
Are sarcodines parasitic or free living?
Most sarcodines are free living; others are parasitic. One of these parasites is the causative organism of amebic dysentery. With the exception of chloroplasts, sarcodines are identical to the ameboid members of the phylum Chrysophyta.
