SCIENTIFIC NAMES They are the specific and distinguishable names given to organisms by the scientists for the removal of ambiguity and to make the name worldwide acceptable by other scientists. Scientific names are based on i. According to principal and criteria of science ii. Acceptable worldwide iii. Help scientists to use same name in any part of the world iv. Should be distinct and different for each species v. New and not used for earlier organisms BINOMIAL NOMECLATURE It is...

TANONOMIC CATEGORIES Taxonomic Category is a unit of grouping of any level used in taxonomy or classification of organisms. Usually there are seven obligate and few intermediate categories used in taxonomy. Hierarchy of categories It is a system in which members of a type are organized in rank on above the other. Hierarchy of categories or taxonomic hierarchy is the system of arrangement of taxonomic categories in a descending order depending upon their relative dimensions. It was introduced by Linnaeus and is therefore also called Linnaean hierarchy or taxonomic hierarchy . Linnaeus proposed five categories- class, order, genus, species, and variety. The latter worker deleted the category of variety and added the categories of kingdom, phylum/division, and family The taxonomic categories which are always used in hierarchical classification of organisms are called obligate categories . They are seven in number . Obligate categories in descending order...

Cell Cell is basic structural and functional unit of life. Because each organism is made up of cell or cells. So that’s why the structure of the organism is due to the presence of cell or cells. The function performed by the organism is due to the function occurs in the cell. The cells are of two types 1. Prokaryotic Pro means 'first' or 'before' and karyotic means ‘Nucleus’. So this refers as the 'The Cell with First nucleus' OR 'The Cell Come before the first Nucleus' . · Well defined nucleus is absent, so the genetic material is called as ‘NUCLEOID’. · Cytoplasm is present and consists of Biomolecules, water, salts, Ions Etc. This performs the chemical reactions to support life. · Cell membrane is also present which covers the...

DIVERSITY IN THE LIVING WORLD Earth has 1.7 to 1.8 million known organisms. Each organism represents a distinct species. All the species differ from one another. This variability present among organisms, their members and communities is called Biodiversity. Nomenclature This means providing the proper, specific and distinguishable name to each and every organism. Common or Vernacular names They are local names which are given to organisms in particular region and language by local persons. Each region, tribe and language has its own specific names for organisms known in the area so that they can be properly identified. E.g. Region(language) Specimen English Rose Hindi Gulab Bangali Golap Tamil Rojapo Advantages · Common Names are brief e.g., onion or pyaz. · They are based on some feat...

LIFE Life is unique, complex organizations of Cell and Cellular contents that show various types of functions and processes to bring the life existence. OR Life is unique, complex organization of atoms, molecules and compounds, which perform several chemical reactions for the existence of life. LIVING Passing through or going through the life processes and function due to several chemical reactions is called Living. Characteristics of living organisms 1. Individuality . Each living organism has its own unique presence, which cannot be divided further into more independent parts. E.g. a dog has its individuality from rest of the animals due it own unique Morphology (how the organism look from outside or it appears. 2. Definite shape and size . Every organism has definite shape and size which help in the recognition of the orga...

TAXONOMY It is the study of rules, principle and practice of classification, identification and nomenclature of an organism. The term was coined by de candolle . Carolus Linnaeus is known as the Father of taxonomy . Taxonomic studies are based on the comparative study of morphology, cytology, embryology, molecular biology, etc. This gives the information about the similarities, dissimilarities and evolutionary relationship. PHYLOGENY It is the evolutionary history or lineage of one or more groups of organisms. It is based on the study of fossils, comparative anatomy and other fields of study. SYSTEMATIC The science which deals with identification, description, classification and nomenclature based on unique properties of every species and group of species at every level of classification. The term was coined by C.Linnaeus. It is often interchangeable with taxonomy . PROCESSES BASIC TO TAXANOMY There are four basic processes of taxonomy- ...

CLASSIFYING A GROUP OF SPECIES OR REVISION GROUP Revision of group is the delimitation (separation) of species by finding out the common characters amongst species and placing them successively into higher taxonomic categories (order, family, class, etc) on the basis of their similarities and evolutionary relationship (patterns of descent of organism or evolutionary tree of an organism). In sexually reproducing organisms, reproductive isolation (separation) from other and free interbreeding amongst members under natural conditions is the best criteria for delimitation of species. Evidence from morphology (study of outer structure), anatomy (study of internal structures), embryology (study of embryo), cytology (study of cell), chromosomes, and molecular biology are used to support of the same. In organism reproducing asexually, morphotaxonomy (classifying the organism on the basis of morphology), cytotaxonomy (classifying the organism on the basis of cell structure an...

IDENTIFICATION It is the process of finding the correct place in a system of classification and finding out the correct name of the organism. It is just like locating a title in the library on the basis of knowledge of its subject title and name of the author. Identification is carried out with the help of keys. CLASSIFICATION Biological classification is the scientific arrangement in a hierarchical series of groups and sub groups on the basis of similarities and dissimilarities in their characters so as to bring out their relationship. It is just like arranging the books in a library subject wise, title wise and author wise in a proper sequence. Need of classification 1. It is not possible to identify an organism without any system of classification. 2. New organisms are discovered every year therefore it is required to have system of classification to find out correct resemblance. 3. ...
