Define and understand the following terms:
(i) Phylum (ii) Class (iii) Family (iv) Order (v) Genus
Answers
According to the taxonomic classification, all the species are arranged in a specific chronological order.
Step by step explanation:
i) Phylum: According to biology, phylum is defined as the taxonomic rank present below kingdom and above class. Example: Chordata, Arthapods etc.
ii) Class: Class is defined as a distinct taxonomic rank in the biological classification system. It is identified through a discrete name and reflects the specific morphological characteristics of the comprising species. Example: class Mammalia belongs to phylum Chordata.
iii) Family: It is defined as one of the eight major unit in the hierarchical classification. It is essentially classified between order and the genus. The family is further sub-divided into subfamilies portraying intermediate characteristics between the family sharing common attributes. Example: Walnut trees and hickory trees constitute family Juglandaceae.
iv) Order: It is defined as a taxonomic rank that helps in the classification of organisms. It is placed under class and constitutes organisms comprising similar attributes and phenotype. Example: Order primates, order carnivora etc.
v) Genus: It is defined as a taxonomic unit that is placed above species and below family. It includes species of common traits and phylogeny relationships.
Explanation: According to the taxonomic classification, all the species are arranged in a specific chronological order. This helps the scientists to classify them and study the distinct characteristics of all species in a systematic manner.
