Phylum is a primary division of the animal kingdom, the major taxonomic group of plants and animals which further contain classes. Organisms are divided in kingdoms,phyla, classes to make it easy for research and clarity in this vast range of different variety of organisms.
Different classes of organisms are grouped into the next larger category called "phylum" in taxonomy. This grouping is based on similarities in body plan and development.
The phylum that includes segmented worms is known as Annelida. These phylum is believed to have over 17,000 species of different organisms.
Phylum is the stage above class and below kingdom. There are two categories in phylum: eukaryote and prokaryote. Eukaryotes have well defined cell membranes and nuclei, while a prokaryote doesn't. This can already separate the different classes into different categories, which is evidently the goal of taxonomy -- to classify organisms.
A group of classes make up a phylum in biology. Phylum is a higher taxonomic rank in the classification of organisms, lying below kingdom and above class. Organisms belonging to the same phylum share certain common characteristics.
Phylum Ciliophora
An example of two organisms in the same class but different orders is a lion (order: Carnivora) and a horse (order: Perissodactyla). Both belong to the class Mammalia, but they are classified under different orders based on their biological characteristics and evolutionary history.
The phylum that has organisms known for a hydrostatic skeleton is the phylum Mollusca. This group of animals, such as snails and squids, have a fluid-filled cavity that provides support and structure to their bodies.
Phylum Chlorophyta
Te organisms found in the phylum chorodata are sea squirts and vertebrate animals.
roundworms
The phylum that includes all organisms with a backbone is Chordata. This phylum encompasses animals such as mammals, birds, reptiles, amphibians, and fish. The presence of a notochord or backbone is a defining characteristic of organisms within the Chordata phylum.
it contains organisms such as bacteria and other diseases. phylum is very dangerous to humans if phylum touches you then you have 1 hour to clean it off or you will die.
