Define and understand the following terms phylum

(i) Phylum- Phylum is the primary division of kingdom. It includes one or more related classes of animals. In plants, instead of phylum, the term ‘division’ is used. (ii) Class- Class is a taxonomic group consisting of one or more related orders. For example, the class, Mammalia, includes many orders. (iii) Family- Family is a taxonomic group containing one or more related genera. In plants, families are categorized on the basis of vegetative and reproductive features. (iv) Order- Order is a taxonomic group containing one or more families. For example, the order, carnivore, includes many families. (v) Genus – Genus is a taxonomic group including closely related species. For example, the genus, Solanum, includes many species such as nigrum, melongena, tuberosum, etc. For more answers visit to website:

(a) Domain - Kingdom - Phylum - Class - Order - Family -Genus - Species (b) Kingdom - Domain - Class - Phylum - Order - Family - Genus - Species (c) Kingdom - Domain - Class - Phylum - Order - Genus - Species - Family (d) Kingdom - Class - Phylum - Domain - Genus - Order - Family - Species

Phylum– Phylum is a category higher than that of Class. The term Phylum is used for animals. A Phylum is formed of one or more classes, e.g., the Phylum Chordata of animals contains not only the class Mammalia but also Aves (birds), Reptilia (reptiles), Amphibia (amphibians), etc. In plants the term Division is used in place of Phylum

Phylum - Phylum is a category higher than that of Class. The term Phylum is used for animals. A Phylum is formed of one or more classes, e.g., the Phylum Chordata of animals contains not only the class Mammalia but also Aves (birds), Reptilia (reptiles), Amphibia (amphibians) and Pisces(Fishes). In plants the term Division is used in place of Phylum. Class - A Class is made of one or more related Orders. For example, the Class Dicotyledoneae of flowering plants contains all dicots which are grouped into several orders (e.g., Rosales, Sapindales, Ranales, etc). Family - It is a taxonomic category which contains one or more related genera. All the genera of a family have some common features or correlated characters. They are separable from genera of a related family by important and characteristic differences in both vegetative and reproductive features. E.g., the genera of cats (Fells) and leopard (Panthera) are included in the Family Canidae (dogs, foxes, wolves). Similarly, the family Solanaceae contains a number of genera like Solanum, Datura, Petunia and Nicotiana. They are distinguishable from the genera of the related family Convolvulaceae (Convolvulus, Ipoloea). Order - The category includes one or more related families. E.g., the plant Family Solanaceae is placed in the Order Polemoniales along with four other related families (Convolvulaceae, Boraginaceae, Hydrophyllaceae and Polemoniaceae). Similary, the animal families Felidae and Canidae are included under the ...
