Light duration or photo period affects many seasonal breeders, plants as well as animals. (ii) The description of characteristics helps in the placement of the organism in various taxa. The various external factors to which living organisms respond are light, water, temperature, pollutants, other organisms, etc. This ensures that the student can easily understand what is being said. (i) Species is the basic unit of taxonomy, that can be described on the basis of one or few preserved specimens. The keys generally use two contrasting characters called couplet. The earth serves as a home for diverse living organisms. Taxonomy A new organism can be given a new name after following the standardized rules. Nomenclature In 1961, Simpson, defined systematics as the study of diversity of organisms and all their comparative and evolutionary relationships based on comparative’ anatomy, physiology, biochemistry and ecology. Finally, many organ systems organise and form a living organism. These gardens generally have facilities like library, laboratory, herbarium and museum. STUDY. Rules of binomial nomenclature were initially framed by Linnaeus in his books, Species Plantarum and Systema Naturae. It is almost impossible to study all the living organisms.

(c) Zoos are the centres for conservation of threatened and rare animal species. For example, bone is a hard tissue, which provides framework to the body. … (iii) A new taxon can be framed if the organism is different from the existing taxa. Class (Linnaeus) is a major category, which includes related orders. Sometimes, specimens are also preserved for future studies. It involves hierarchy of steps in which each step represents a rank or category. (c) different for each species and not used for other organisms earlier. It is the story of evolution of living organisms on the earth. These sheets are arranged further according to a universally accepted system of classification. Each character in this case is given a number in brackets. 2. (b) These are the centres for recreation and education.

(e) It becomes easy to know the features of whole group by studying one or two organisms of the group. (iii) The names are small and comprehensive. Carolus Linnaeus is known as father of taxonomy. Therefore, consciousness can also said to be a defining property of living organisms. For example, Mangifera indica (mango), Solarium tuberosum (potato) and Panthera leo (lion). For Study plan details. But in, these characters are not separated by intervening sub-dividing characters. In multi cellular organisms in particular, growth occur by cell division or increase in number of cells. (a) The zoological parks increase understanding of wildlife. (v) Biological delimitation includes various branches of systematics, e.g., Cytotaxonomy, experimental taxonomy, numerical taxonomy, chemotaxonomy, etc. Physical and Biological Hierarchies Reproduction, a characteristic of living organisms is the process of producing offsprings, possessing features similar to those of parents. Question 2. (ii) The first word in a biological name represent the genus while, the second component denotes the specific epithet. Major characteristics of living organisms are given below Test. Linnaeus used Systema Naturae as the title of his book. Growth occurs continuously throughout life in plants, whereas, in animals, it occurs up to a certain age only. All living organisms along with their ancestors and descendants are linked to one another by sharing of common genetic material in the form of DNA in varying degrees. It aims at finding the correct name and appropriate position of an organism. However, taxonomists have also developed sub-categories in this hierarchy to facilitate more sound and scientific placement of various taxa. A plant family ends in a suffix -aeae and sub-family -oideae. Similarly, all the plants are kept in kingdom—Plantae. In other words, genera are aggregates of closely related species.
