Question

Sarcodines are
A. Sporozoans
B. Ciliated protozoans
C. Amoeboid protozoans
D. Flagellated protozoans

Answer 1

Hint: Protozoan of the superclass is called Sarcodine. Temporary cytoplasmic extensions are called pseudopodia. Locomotion contains a streaming cytoplasm, this process is called an amoeboid movement and also we can call it as feeding.

Complete answer:
> Sporozoans: Sporozoans is a very old taxon, which was first described and experienced in 1879 by a German zoologist known as Karl Georg Friedrich Rudolf Leuckart. Nowadays, instead of this phylum Apicomplexa is suggested for use.
Hence, option (A) is incorrect.
> Ciliated proptozoans: A batch of protozoans characterized by the presence of hair-like organelles called cilia. And, these ciliates are a group of protozoans. Sarcodina is the largest phylum of protozoans. Sarcodines are Ciliated protozoans
Hence, option (B) is correct.
> Amoeboid protozoans: Amoeba, which can also be spelt as amoeba. And, in plural amoebas and also amoebae. Microscopic unicellular protozoans of the rhizopoda will order Amoebida, that too in any order. It is a very well-known type of species in biology. Amoeba proteus, which are found on decaying bottom vegetation naturally and also from freshwater streams and ponds. Parasitic amoebas are in numerous forms.
Hence, option (C) is incorrect.
> Flagellated protozoans: Flagellate is mostly an uninucleated organism which will be possessed at some time in the life cycle. And also, it is of type one too many flagella for locomotion and also sensation.
Hence, the option (D) is also incorrect.

Hence, the correct answer is option (B).

Note: Sarcodina is the largest phylum of protozoans. It mainly includes amoebas and other related organisms. Most of the Sarcodines are free-living but some of them are parasitic, too. The Genus Amoeba and also pathogenic species will be included in Sarcodines. The best example of Sarcodines is dysentery, which causes Entamoeba histolytica. The shape of these protozoan cells may be spherical or irregular in shape. If necessary these will turn an external shell or skeleton, nothing but see radiolarian.
