The following article is from The Great Soviet Encyclopedia (1979). Rhizopoda a subclass of protozoans capable of forming temporary cytoplasmic protuberances, or pseudopods, which serve for movement and for capturing food (certain amoebas, as well as rhizopod gametes, form temporary flagella). It might be outdated or ideologically biased. Find the perfect nonion stock photo. Storer And Usinger : They gave the modern classification of the 5-kingdom system. 2.

(1980) placed gromiids in the phylum Sarcomastigophora, subphylum Sarcodina, superclass Rhizopoda, class Filosea, order Gromiida, describing them as organisms with a body enclosed by a test or rigid external membrane, and possessing a distinct aperture. Foraminiferan, any unicellular organism of the rhizopodan order Foraminiferida (formerly Foraminifera), characterized by long, fine pseudopodia that extend from a uninucleated or multinucleated cytoplasmic body encased within a test, or shell. Mastigophora is a phylum of unicellular heterotrophic protozoans of the kingdom Protista. CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): been analyzed for their foraminifera content. In modern classification the animals have been classified into 10 major and 21 minor phylum. 1. The marine Quaternary deposits of borings I, II and III consist mainly of clay, here called the Lundergård Clay. 3. ADVERTISEMENTS: In this article we will discuss about:- 1. In their revised classification of the Protozoa, Levine et al. Classification 4. Reproduction. 1.3 Types of Species. The Rotaliida (Delage and Hérouard, 1896) is a highly diverse order of Foraminifera comprising more than 250 genera populating marine habitats from shallow water to deep sea (Haynes, 1981).Rotaliid foraminifera are basically defined by calcareous hyaline perforate tests. 4. Brady, H.B., 1879, Notes on some of the Reticularian Rhizopoda of the Challenger expedition, Part 1. Cellular Characteristics of Protozoa 3. Rhizopoda are a group of protozoan amoeboid organisms and possess locomotory organs in the form of cilia. 1. Rhizopoda (foraminifera and polycystina) of the north polar expedition of 1875-1876: Annals and Magazine of Natural History, Ser.5, v. 1, p.525-440. Suctoria are ciliates, which become sessile in their developed stage. 5).
