Biology class 11 Chapter-1 Meium part 10 Welcome to your Biology class 11 Chapter-1 Meium part 10 Read the following statements. (a) Isolated metabolic reactions in-vitro are living things.(b) Reproduction is synonymous with growth in Chlamydomonas.(c) Reproduction is an all inclusive defining characteristic of living organisms.(d) Plants have an ability to respond to external factors. How many of the above statements is/are not true? One Two Three Four None Consider the following statements and select the correct set of statements from the options. (A) The most obvious and technically complicated features are metabolism and consciousness.(B) Datura, Petunia and Solanum are placed in the family Solanaceae.(C) Generally, families and orders are identified on the basis of aggregates of vegetative characters only.(D) Class mammalia includes orders like Primata and Carnivora. (B), (C) & (D) (A), (C) & (D) (B) & (D) (A), (B), (C) & (D) None Read the following statements carefully and choose the correct option. In plants, growth by cell division occurs continuously only in meristematic cells and that too for a specified period of time. Living organisms are self-replicating, evolving and self-regulating interactive systems but are not capable of responding to external stimuli. Nomenclature standardises the naming of living organisms such that a particular organism is known by the same name all over the world. Classification is a single step process None Which of the following statements are correct? (A) Scientific names are derived from Latin.(B) In the case of Amoeba, reproduction is not synonymous with growth.(C) As Latin is a dead language, there is little likelihood of changes in meaning and spelling of names with time.(D) Species included in a genus resemble in many features. (A), (B) and (C) (A) and (D) (A), (C) and (D) (B), (C) and (D) None Which of the following statements is incorrect? Conservative characters are more useful in classification Linnaeus is regarded as the father of taxonomy Binomial names are Latinised or derived from Latin irrespective of their origin.

None These questions consist of two statements each, printed as Statement-I and Statement-II. While answering these questions, you are required to choose any one of the following four responses. Statement-I: In binomial nomenclature, the first word is specific epithet.Statement-II: In binomials, when handwritten, underlining indicates their Latin origin. Both Statement-I and Statement-II are correct. Both Statement-I and Statement-II are incorrect Statement-I is correct & Statement-II is incorrect Statement-I is incorrect & Statement-II is correct. None These questions consist of two statements each, printed as Statement-I and Statement-II. While answering these questions, you are required to choose any one of the following four responses. Statement-I: Biology is the story of life on earth.Statement-II: All living organisms are linked to one another by the sharing of the common genetic material. Both Statement-I and Statement-II are correct Both Statement-I and Statement-II are incorrect Statement-I is correct & Statement-II is incorrect Statement-I is incorrect & Statement-II is correct. None These questions consist of two statements each, printed as Statement-I and Statement-II. While answering these questions, you are required to choose any one of the following four responses. Statement-I: Families are characterised on the basis of both vegetative and reproductive features of plant species.Statement-II: Families consist of a group of related genera with fewer similarities compared to genus and species. Both Statement-I and Statement-II are correct. Both Statement-I and Statement-II are incorrect. Statement-I is correct & Statement-II is incorrect Statement-I is incorrect & Statement-II is correct None These questions consist of two statements each, printed as Statement-I and Statement-II. While answering these questions, you are required to choose any one of the following four responses.Statement-I: Cellular architecture of the body is the defining feature of life forms.Statement-II: Metabolic reactions cannot be demonstrated outside the body in cell free system Both Statement-I and Statement-II are correct. Both Statement-I and Statement-II are incorrect Statement-I is correct & Statement-II is incorrect. Statement-I is incorrect & Statement-II is correct None Fill the taxonomic category in the empty box by marking an option.Order → →Phylum or division Family Class Genus Kingdom None Arrange the following taxonomic categories in ascending order of hierarchy: (A) Family (B) Order(C) Genus (D) Class Choose the correct sequence from the options given below: (C), (A), (B), (D) (C), (A), (D), (B) (A), (C), (B), (D) (D), (B), (A), (C) None Which of the following are essential processes for defining living organisms? (A) Metabolism(B) Reproduction(C) Growth(D) Ability to sense the environment(E) Cellular organization Choose the correct group of processes from the options given below: (A), (B), and (C) only (A), (D) and (E) only (B), (C), and (D) only (A), (C), and (E) only None Read the following statements and select the correct ones. (A) Increase in mass and increase in number of individuals are twin characteristics of growth.(B) Metabolic reactions can be demonstrated outside the body in an isolated cell-free system.(C) In unicellular organisms, reproduction is synonymous with growth. (A) and (B) (B) and (C) (A) and (C) All of these None Which of the following statements is not correct? Biodiversity is occurrence of variety of life forms differing in morphology, anatomy, habitats and habits Systematics is the branch of biology that deals with cataloguing plants, animals and other organisms into categories that can be named, remembered, compared and studied. Taxonomy is the branch of biology that deals with principles and procedures of identification and nomenclature of organisms Biodiversity is the study of aquatic life forms on the basis of morphological features only None Select the incorrect statement with respect to the taxon, 'genus'. It is a group or assemblage of related species. A genus essentially possesses more than one number of species. Lion, Tiger, Leopard are closely related species which have been placed in the genus Panthera and are respectively named as Panthera leo, P. tigris and P. pardus. Solanum, Mangifera, Musca and Triticum are the examples of genera. None Scenario: Imagine you are a researcher, tasked with classifying new discoveries into relevant taxa. You stumble upon a mysterious organism that exhibits characteristics of both plants and animals - it has leaf-like structures but also shows locomotionBased on the scenario, which statement would be most accurate in the context of taxonomy and systematics? You would have an easy time classifying the organism since it has observable characteristics. The organism can only be classified into one taxa, either as a plant or as an animal, but not both. The scenario presents an opportunity to perhaps define a new taxa at a different level due to the unique combination of characteristics. Because the earliest classifications were based on 'uses,' you would primarily focus on the organism's potential utility for food, clothing, or shelter None As we go from species to kingdom in a taxonomic hierarchy, the number of common characteristics: Will decrease Will increase Remain same May increase or decrease None Which of the following 'suffixes' used for units of classification in plants indicates a taxonomic category of 'family'? -Ales -Onae -Aceae -Ae None The term 'systematics' refers to: Identification and study of organ systems Identification and preservation of plants and animals Diversity of kinds of organisms and their relationship Study of habitats of organisms and their classification None Genus represents: An individual plant or animal A collection of plants or animals Group of closely related species of plants or animals None of these None The taxonomic unit 'Phylum' in the classification of animals is equivalent to which hierarchical level in classification of plants: Class Order Division Family None In the taxonomic categories which hierarchial arrangement in ascending order is correct in case of animals? Kingdom, Order, Phylum, Class, Family, Genus, Species Kingdom, Phylum, Class, Order, Family, Genus, Species Kingdom, Class, Phylum, Family, Order, Genus, Species Kingdom, Order, Class, Phylum, Family, Genus, Species None Which one of the following belongs to the family Muscidae? Grasshopper Cockroach Housefly Fire fly None Select the correctly written scientific name of Mango which was first described by Carolus Linnaeus Mangifera indica Car. Linn. Mangifera indica Linn. Mangifera indica Car. Mangifera Indica None Time's up
