Which of the following protozoa belongs to subphylum Sarcodina?

Which of the following protozoa belongs to subphylum Sarcodina?

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.

What is the habitat of Sarcodina?

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.

What makes up 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.

What are some examples of Sarcodina?

Rhizopoda
Heliozoa
Sarcodina/Lower classifications

Where do most of the species of Sarcodina live?

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.

How many species are in the Sarcomastigophora phylum?

· Classes: The phylum Sarcomastigophora is further divided into two sub-phyla that include: * In some books, Sarcodina and Mastigophora is ranked as superclass rather than sub-phyla. Also referred to as the amoebas in some books, the sub-phyla Sarcodina consists of over 13,500 species that move and feed by means of pseudopodia.

What makes a sarcodine a free living organism?

Sarcodina. 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. One of these parasites is the causative organism of amebic dysentery.

How does a Sarcodina move with its pseudopodia?

They are amoebas and are a blob of protoplasm formed in a single cell. By flowing their protoplasm forward into a “foot” then bringing the rest of their body into the foot, they can slither along. Some Sarcodina have firm axial rods instead of pseudopods. They move by motion in these rods.
