What is the largest division of a kingdom?
Kingdom Animalia is the largest of the five existing kingdoms on Planet Earth. The scientific classification system is divided into seven major groups, (1) kingdom, (2) phylum or division, (3) class, (4) order, (5) family, (6) genus, and (7) species. The kingdom is the largest group and a species is the smallest.

Placozoa is the smallest phylum in the animal kingdon with only one identified species.
What is the oldest phylum?
The answer to the question of whether the sponges or the comb jellies (also known as sea gooseberries) represent the oldest extant animal phylum is of crucial importance to our understanding of organismic evolution.

On what basis Kingdom Animalia is classified?
The major group of animals are classified under the Kingdom Animalia, also known as Metazoa. This kingdom does not contain prokaryotes. All the members of this kingdom are multicellular, eukaryotes. They are heterotrophs, they depend on other organisms directly or indirectly for food.
Which is the largest cell in Kingdom Animalia?
The Animalia Kingdom is the largest of all kingdoms with more than one million species!
What is the largest division of plants?
In botany, the equivalent of a Phylum is called a Division. The Kingdom Plantae is divided into 14 Divisions. A Division (pl. Phyla) is the largest formal major grouping within plant taxonomy below Kingdom.
Which is the largest phylum of animal kingdom?
Arthropod, any member of the phylum Arthropoda, the largest phylum in the animal kingdom, which includes such familiar forms as lobsters, crabs, spiders, mites, insects, centipedes, and millipedes. About 84 percent of all known species of animals are members of this phylum.
What are the 8 levels of classification in order from broadest to most specific?
Linnaeus developed a system that went from broadest to most specific. The levels of classification he used are: kingdom, phylum, class, order, family, genus, and species. You can see that genus and species are the two most specific categories, which is why they are used in binomial nomenclature to identify an organism.
What are the six kingdoms in order from least to most complex?
Six Kingdoms-Simplest to Most Complex-Final Grade 8
- first. archeobacteria.
- second. eubacteria.
- third. protista.
- fourth. fungi.
- fifth. plantae.
- sixth. animalia.
What are the 5 kingdoms and their characteristics?
Five Kingdom Classification System
- Monera (includes Eubacteria and Archeobacteria) Individuals are single-celled, may or may not move, have a cell wall, have no chloroplasts or other organelles, and have no nucleus.
- Protista.
- Fungi.
- Plantae.
- Animalia.
- A “mini-key” to the five kingdoms.
What are the 5 kingdoms and examples of each?
The five-kingdom system of classification for living organisms, including the prokaryotic Monera and the eukaryotic Protista, Fungi, Plantae and Animalia is complicated by the discovery of archaebacteria.
What is the largest phylum in the plant kingdom?
Angiosperms (flowering plants) are the largest Phylum in the plant kingdom Plantae.
Do Placozoans have a nervous system?
Interestingly enough, placozoans contain cells, which are dispersed around their outer edge, that react with antibodies against a neuropeptide that is present in the nervous system of cnidarians. Furthermore, placozoans are so cryptic that their diversity might be much greater than we realize.
How many phyla are there in the plant kingdom?
12 phyla
Which phylum is the simplest and oldest?

Did cnidarians evolved from sponges?
In their own primitive way, sponges have no symmetry, and no organ systems. An ancient line of sponges evolved into a more advanced group – the Cnidarians. In the evolution of Cnidarians, new achievements were made. Cnidarians have radial symmetry, a better body design than no symmetry at all.
Which is largest cell?
The largest cells found in nature are ostrich eggs. Before fertilization, the entire interior of the egg consists of a single cell, which can weigh up to 5 pounds. The largest single-celled organism is an animal called Syringammina fragilissima, which can grow to a width of 4 inches.
Are bacteria part of the animal kingdom?
Bacteria are neither animals nor plants. Living things are classified into five kingdoms: animals belong to Kingdom Animalia, plants belong to Kingdom Plantae, fungi to Kingdom Fungi, protists to Kingdom Protista and bacteria is classified under their own kingdom known as Kingdom Monera.
