Systematics Welcome to your Systematics 1. Which of the following criterion is NOT used for the classification of organisms Mode of nutrition Time of one life span Mode of reproduction Cell structure None 2. Which of the following environment where life forms never survive, Deciduous forests Ocean Hot springs None of the above None 3. What is an open type circulatory system in animals? Blood does not flow through the blood vessels and directly baths the cells in it thus heart is absent. Blood does not flow through the blood vessels and directly baths the cells in it when heart pumps the blood Primary level of the blood vessels is observed The circulatory system directly transact the compounds directly form the environment None 4. Which of the following of the correct order of the taxonomic hierarchy? Kingdom-Division_Class-Order-Family-Genus-Specie Phylum-Kingdom_Class-Order-Family-Genus-Specie Kingdom-order_Class-Divsion-Family-Genus-Specie Kingdom-Division_Family-Order-class-Genus-Specie None 5. Which of the following is true about the sporophyte of the bryophyte It is multicellular body It is not a free living entity and its dependent on parent plant for the nourishment After fertilisation sporophyte exists as a free living entity The fertilisation take place as a result of the male and female individuals None 6. Binomial nomenclature, Consists of two parts of the name one genus and other is species Requires minimum two morphological characters mentioned in the name Must have same common name and scientific name None of the above None 7. In polynomial nomenclature, People used descriptions to assign the name of the species More than one individual and distinct names were assigned to a single species Names were continuously revised for improvisation None of the above None 8. Which of the following is NOT TRUE for cell division in plants and animals? Growth of the multicellular organisms take place through cell division Plants grow throughout their lifespan Animals grow throughout their lifespan After certain age cell division in animals is mainly required for filling up the lost cells None 9. Which of the following best explain why archaebacteria survive in the extreme environment They have very stable DNA than any other bacteria Increased temperature does not lead to conformational changes in their protein They have different cell wall than normal bacteria which contributes to the survival in the extreme environment. 4. None of the above None 10. What are algae? Algae is an autotrophic life form found only in fresh water Algae is an autotrophic life form found in fresh water and marine water They are also found in association with fungi II & III I & III None 11. Which of the following is NOT the part of a circulatory system? Arteries Coeloms Veins Capillaries None 12. What are zoospores? They are motile They mediate the asexual reproduction Algae reproduce through zoospore All of the above None 13. Which of the following is TRUE about the trinomial nomenclature system? It is an extension of the binomial system on special occasion It involves three part name of the individual It consists of genus, species and sub-species elements in the name All of the above None 14. Common mode of reproduction in algae is/are Vegetative mode of reproduction Sexual reproduction Asexual mode of reproduction All of the above None 15. The scientific name of the organism need not to be followed by the name of the discoverer True False None Time's up
