Which out of the following is a mismatched pair of protozoa group and ...
Explanation:
Protozoa are unicellular eukaryotic organisms that can be classified into various groups based on their modes of locomotion and other characteristics. The four major groups of protozoa are amoeboid protozoa, flagellated protozoa, ciliated protozoa, and sporozoans.
a) Amoeboid protozoan - Entamoeba histolytica: Entamoeba histolytica is an example of an amoeboid protozoan. Amoeboid protozoa move by using pseudopodia, which are temporary extensions of the cell's cytoplasm.
b) Flagellated protozoan - Giardia intestinalis: Giardia intestinalis is an example of a flagellated protozoan. Flagellated protozoa move by using one or more whip-like extensions called flagella.
c) Ciliated protozoan - Paramoecium caudatun: Paramoecium caudatum is an example of a ciliated protozoan. Ciliated protozoa move by using hair-like structures called cilia.
d) Sporozoan - Leishmania donovani: Leishmania donovani is not a sporozoan. It is actually a parasitic protozoan that belongs to the genus Leishmania.
Sporozoans are a group of protozoa that are characterized by their ability to form spores during their life cycle. Examples of sporozoans include Plasmodium (which causes malaria) and Toxoplasma gondii (which causes toxoplasmosis).
Therefore, the mismatched pair of protozoa group and its example is d) Sporozoan - Leishmania donovani.
Which out of the following is a mismatched pair of protozoa group and ...
Explanation:
Protozoa are unicellular eukaryotic microorganisms that can be classified into four major groups based on their mode of locomotion and other characteristics: amoeboid, flagellated, ciliated, and sporozoan. Each group has its own unique features and examples.
(a) Amoeboid protozoan - Entamoeba histolytica: Amoeboid protozoa move by extending their pseudopodia, which are temporary cytoplasmic projections. Entamoeba histolytica is a pathogenic amoeboid protozoan that causes amoebiasis, an infection of the large intestine.
(b) Flagellated protozoan - Giardia intestinalis: Flagellated protozoa move by the use of one or more flagella, which are long, whip-like structures. Giardia intestinalis is a flagellated protozoan that causes giardiasis, a diarrheal illness.
(c) Ciliated protozoan - Paramoecium caudatun: Ciliated protozoa move by the use of numerous hair-like structures called cilia. Paramoecium caudatun is a ciliated protozoan that is commonly used as a model organism in scientific research.
(d) Sporozoan - Leishmania donovani: Sporozoan protozoa are non-motile and typically have complex life cycles that involve multiple hosts. Leishmania donovani is not a sporozoan but a flagellated protozoan that causes leishmaniasis, a disease that affects the skin and internal organs.
Therefore, option (d) is the mismatched pair of protozoa group and its example.
