What is the basic of phylum protozoa classification?

The basis of classification is locomotory organs.

What are the four classes of phylum protozoa?

Protozoa can be divided into four phyla based on their locomotion: Mastigophora, Sarcodina, Ciliophora, and Sporozoa.

What are the 7 phylum of protozoa?

Seven phyla of PROTOZOA are accepted in this classification–SARCOMASTIGOPHORA, LABYRINTHOMORPHA, APICOMPLEXA, MICROSPORA, ASCETOSPORA, MYXOSPORA, and CILIOPHORA. Diagnoses are given for these and for all higher taxa through suborders, and reporesentative genera of each are named.

How many classifications of protozoa are there?

The classification of the protozoa is based on the modified form of that proposed by Levine et. al. (1980). The subkingdom Protozoa is divided into 7 phyla of which 4 mainly Sarcomastigophora, Apicomplexa, Microspora and Ciliophora have representative that are parasitic.

What are the main characteristics of phylum protozoa?

Protozoa are unicellular eukaryotic microorganisms lacking a cell wall and belonging to the Kingdom Protista. Protozoa reproduce asexually by fission, schizogony, or budding. Some protozoa can also reproduce sexually. Relatively few protozoa cause disease.

What are three main types of protozoa?

The protozoa that are infectious to humans can be classified into four groups based on their mode of movement: Sarcodina – the ameba, e.g., Entamoeba. Mastigophora – the flagellates, e.g., Giardia, Leishmania. Ciliophora – the ciliates, e.g., Balantidium.

What is the largest group of protozoans?

xenophyophores
The largest protozoa are called xenophyophores, which can measure up to 20 centimeters in diameter. Protozoa prefer living in moist and aquatic habitats. Their cysts can be found in the bleakest parts of the ecosphere. Protozoa are found drifting in the oceans, seas, and freshwater.

What are the four classes of phylum?

Phylum Protozoa is divided into four classes on the basis of…
  • A. Nuclear structure.
  • B. Locomotoy structure.
  • C. Mode of reproduction.
  • D. Mode of nutrition.

What are the 4 major classifications of protozoa and their unique characteristics?

What Is a Protozoa? Protozoans consist primarily of eukaryotic and single-celled organisms. They are represented by four major groups: Flagellates, Ciliates, Sarcodina, and Sporozoans. In some systems of biological classification, protozoan is a high-level taxonomic group.

What class is the phylum protozoa Locomotory?

So, the correct answer is ‘(C) Sporozoan. ‘ Note: Pseudopodia is a type of locomotory apparatus that is usually observed in the protozoans belonging to the group of Sarcodina or Rhizopoda. These are temporary membranous extensions of the cell membrane for locomotion or for the ingestion of food.

What are protozoans Class 8?

Protozoa: Protozoa are unicellular animals. Some are free-living, others are parasites. Several parasitic protozoans cause diseases in human beings, domestic animals and plants. For example, Plasmodium, a protozoan, causes malaria.

What are three main types of protozoa?

The protozoa that are infectious to humans can be classified into four groups based on their mode of movement: Sarcodina – the ameba, e.g., Entamoeba. Mastigophora – the flagellates, e.g., Giardia, Leishmania. Ciliophora – the ciliates, e.g., Balantidium.

What is the largest phylum of protozoa?

Protozoa vary in size and shape. Their sizes range from 10 to 55 micrometers, but they can be as large as 1 mm. The largest protozoa are called xenophyophores, which can measure up to 20 centimeters in diameter.
