Question

One important phylum of kingdom Animalia of two kingdom systems was removed and placed in kingdom Protista of the five-kingdom system. Name this phylum and give its important features.

Answer 1

Hint: Kingdom is the second taxonomic rank and there are many kingdoms of classification. Here, we are going to find the type of phylum which comes under the phylum Animalia that comes under the two-kingdom system and in the Protista in five kingdom system where it is removed and replaced and with the important features of that phylum. Through some of the points, it could be analyzed.

Complete answer:
The phylum that is removed from the kingdom animalia of the two-kingdom classification and placed in the kingdom Protista of the five-kingdom classification is phylum protozoa. This is an informal group of the eukaryotes of the single cell. These may occur either in free-living or in the parasite. This is a large group. There are about three types of phylum that comes under the phylum protozoa. The following are some of the important features of the phylum protozoa. They are as follows:
-The organisms present here are eukaryotic and unicellular.
-These mostly occur in the aquatic animals.
-Most of them are heterotrophic modes of nutrition.
-Cells are mostly absent here and some of them have either pellicles or form cells.
-These are the microscopic organisms which inhabit water, soil or the parasites.
-The body of them are naked and are covered by the pellicle.
-These possess contractile vacuole for the process of osmoregulation.

These are some of the important features that come under the phylum protozoa. This phylum comes under the two-kingdom system and is shifted to the Protista of five-kingdom system.

Note: This kind of phylum helps in the fertility of the soils and they play a major role in them. These are very much used in the sanitary betterment and in the improvement of the water bodies. These are also consumed as the food. These are some importance of the phylum protozoa.
