      Question 16.
      \nExplain the role of Latin and Greek names in Biology.
      \nAnswer:
      \nAristotle (384 to 322 BC) was the first to classify all animals in his Historia Animalium in Latin. He classified the living organisms into plants and animals. Animals were classified as walking (terrestrial), flying (birds), and swimming (aquatic) based on their locomotion.<\/p>\n

      He classified the animals with red blood cells as Enaima and those without red blood cells as Anima. Though his method of classification had limitations, his contribution to biology was remarkable. Theophrastus did his research on the classification of plants. He was known as the Father of Botany.<\/p>\n

                            \nAnswer:
                            \nGiving three names to the species is meant as trinomial nomenclature.
                            \nWhen members of any species have large variations then a trinomial system is used.
                            \nThe species is classified into subspecies and this is an extension of binominal nomenclature system which has an addition of subspecies. Followed by Genus name species subspecies name is also added.<\/p>\n

                            \nAnswer:
                            \nMany organisms were not fitting into his classification. Frogs have lungs and they are amphibians while their larva, the tadpole is aquatic and respires through gills. It is difficult to classify frogs according to his method. All flying organisms such as birds, bats, flying insects were grouped together. Ostrich, emu and a penguin are flightless birds and hence they cannot be classified by his method.<\/p>\n

                            • Aristotle\u2019s classification system had limitations and many organisms were not fitting into his classification.<\/li>\n
                            • The tadpoles of frog are born in water and have gills but when they metamorphosed into adult frogs they have lungs and can live both in water and on land. There is no answer to this question.<\/li>\n
                            • Based on locomotion birds bats and flying insects were grouped either just by observing one single characteristic feature the flying ability.<\/li>\n
                            • On the contrary to the above-said example, the ostrich emu and penguin are all birds but cannot fly. He did not classify them as birds.<\/li>\n<\/ul>\n

                              • They are capable of synthesizing their food without sunlight and oxygen by utilizing hydrogen sulphide and other chemicals from the volcanic vents.<\/li>\n
                              • Some of them produced methane.<\/li>\n

                                1. Bacterias are prokaryotic.<\/li>\n
                                2. They do not have a definite nucleus and do not have histones.<\/li>\n

                                  \nAnswer:
                                  \nCladistic classification takes into account ancestral characters (traits commons for the entire group) and derived characters (traits whose structure and function differ from the ancestral characters). The accumulation of derived characters resulted in the formation of new subspecies.<\/p>\n
