sarcodine, any protozoan of the superclass (sometimes class or subphylum) Sarcodina. These organisms have streaming cytoplasm and use temporary cytoplasmic extensions called pseudopodia in locomotion (called amoeboid movement) and feeding.

Which is the important feature of class Sarcodina?
The members of the Sarcodina family are known as sarcodines. It compromises amoeba and related organisms. The key feature of the organisms of this class is the presence of pseudopodium, it has a role in trapping food for the ingestion process [performed by the organisms.
What makes Sarcodina unique?
Sarcodina, the largest phylum (11,500 living species and 33,000 fossil species) of protozoans). It comprises the amebas and related organisms; which are all solitary cells that move and capture food by means of pseudopods, flowing temporary extensions of the cell. Most sarcodines are free living; others are parasitic.
What is in the phylum Sarcodina?
A taxonomic group within Phylum Sarcomastigophora. It includes the amoebas, heliozoan, rediozoa and foraminifera, which are characterized by their ability to move by cytoplasmic flow or by pseudopods. Sarcodina, or commonly called sarcodines, include the rhizopods and actinopods.
What type of nucleus is Sarcodina?
In most Sarcodina the nucleus is vesic- ular, i.e., round and bounded by its own membrane, and usually contains a round central endosome or nucleolus or both.
What organisms are included in the Amoebozoans?
The Amoebozoa include several groups of unicellular amoeba-like organisms that are free-living or parasites that are classified as unikonts. The best known and most well-studied member of this group is the slime mold. Additional members include the Archamoebae, Tubulinea, and Flabellinea.
What are the common characteristics of the class Sporozoa?
Sporozoans are organisms that are characterized by being one-celled, non-motile, parasitic, and spore-forming. Most of them have an alternation of sexual and asexual stages in their life cycle.
Is Sarcodina unicellular or multicellular?
Microbiologists often use the terms "amoeboid" and "amoeba" interchangeably for any organism that exhibits amoeboid movement. In older classification systems, most amoebae were placed in the class or subphylum Sarcodina, a grouping of single-celled organisms that possess pseudopods or move by protoplasmic flow.
What does phylum Sarcodina mean?
Medical Definition of Sarcodina
: a subphylum or other taxonomic group of protozoans of the phylum Sarcomastigophora that includes protozoans forming pseudopodia which ordinarily serve as organs for locomotion and taking food — see rhizopoda.
Where are Sarcodina found?
The majority of species live in marine aquatic environments but some occur in fresh water (and are important members of the soil fauna) and some are parasitic in the intestinal tracts of vertebrates and invertebrates.
Does Sarcodina cause disease?
The amoeboids largely constitute the subphylum Sarcodina. The most widespread pathogenic disease caused by this group of organisms is amebiasis or amebic dysentery, which results from an infection of the protozoan Entamoeba histolytica. Infection occurs when cysts on fecally contaminated food or hands are ingested.
What are the characteristics of Mastigophora?
Some of the other important characteristics of Mastigophora include: Majority of dinospores are covered by an outer armor that consists of cellulosic plates. Some of the species contain colored pigments in place of chlorophyll (some of these pigments are neurotoxic) Kinetoplastids contain extranuclear DNA (kinetoplast)
