Chapter (1 ) Lecture number(1) classification of living things and viruses : Classification of living things: Classification: it is mean dividing the living things in to many groups according to their similarities and differences. Taxonomy: it is a branch of biology the classification is studied by it Note : Classification is very necessary because a- biologists estimate that there are about two million kinds of organisms live today on our planet b-new species are continuously being discovered The history of classification: 1- Ancient classification: Before biologists have used observation to classify living things the Greek philosopher Aristotle (350 B.C) : 1- Was the first man who made some attempts on grouping of organisms.2 - He knew only a few kinds of plant and animal. 3- He classified plants as (herbs , shrubs and trees).4 - He grouping animals according to where they lived :( water , land and air ) 2-modren classification : it is discovered by a Swedish biologist (Carolus Linnaeus or Karl van linne ).1- He developed principle of the modern Taxonomy.2- He used binominal nomenclature: it mean two Latin names for each organism the first is a genus and second is a species. for example Homo sapiens is the biological name of human being.  ‫الفصل األول المحاضرة رلم (‪)1‬‬ ‫تصنٌؾ الكائنات الحٌة والفٌروسات‪:‬‬ ‫تصنٌؾ الكائنات الحٌة‪:‬‬ ‫التصنٌؾ‪ٌ :‬مصد بتمسٌم الكائنات الحٌة إلى مجموعات كثٌرة حسب تشابهها واختالفها‪.‬‬ ‫علم التصنٌؾ ‪ :‬هو فرع من فروع علم األحٌاء ٌدرس التصنٌؾ بواسطته‬ ‫مالحظة‪ :‬التصنٌؾ ضروري للؽاٌة أ‪ -‬ألن علماء األحٌاء ٌمدرون أن هنان حوالً ملٌونً نوع من الكائنات‬ ‫الحٌة تعٌش الٌوم على كوكبنا ب‪ٌ -‬تم اكتشاؾ أنواع جدٌدة باستمرار‬ ‫تارٌخ التصنٌؾ‪ -1 :‬التصنٌؾ المدٌم‪ :‬لدٌما استخدم علماء األحٌاء المالحظة (‪ )observation‬لتصنٌؾ‬ ‫الكائنات الحٌة ‪،‬‬ ‫الفٌلسوؾ الٌونانً أرسطو (‪ 353‬لبل المٌالد) ‪ -1 :‬هو الرجل األول الذي لام ببعض المحاوالت لتجمٌع‬ ‫الكائنات الحٌة‪ -2.‬لم ٌكن ٌعرؾ سوى أنواع للٌلة من النباتات والحٌوانات ‪ -3.‬وصنؾ النباتات بأنها‬ ‫(أعشاب وشجٌرات وأشجار)‪ -4.‬صنؾ الحٌوانات على حسب مكان إلامتها‪( :‬الماء وتربة وهواء)‬ ‫التصنٌؾ الحدٌث‪ :‬اكتشفه عالم أحٌاء سوٌدي (كارولوس لٌنٌوس أو كارل فان لٌن)‪ -1.‬طور مبدأ‬ ‫التصنٌؾ الحدٌث‪ -2.‬استخدم التسمٌة الثنائٌة (‪ : )binominal nomenclature‬تعنً اسمٌن التٌنٌٌن‬ ‫لكل كائن حً ‪ ،‬األول جنس والثانً نوع‪.‬على سبٌل المثال ‪ Homo sapiens ،‬هو االسم البٌولوجً‬ ‫لإلنسان‬ ‫‪Answer these Question‬‬ ‫‪Q1/ Define: 1- Classification 2- Taxonomy 3- binominal nomenclature‬‬ ‫‪4- Aristotle 5- Carolus Linnaeus‬‬ ‫‪Q3/ How did Aristotle classified organisms‬‬ ‫‪Q2/ How did Carl von linne classified organisms‬‬ ‫‪Q4/ Give the reason : classification is very necessary‬‬ ‫عدد المراحل التارٌخٌة ?‪Q5/ numerate the historical stages of classification‬‬ ‫للتصنٌؾ‬ Answer the question for chapter 1 : Lecture number (1) Q1/ Define: 1- Classification: it is mean dividing the living things in to many groups according to their similarities and differences 2- Taxonomy: it is a branch of biology the classification is studied by it 3- binominal nomenclature: it mean two Latin names for each organism the first is a genus and second is a species. for example Homo sapiens is the biological name of human being. 4- Aristotle : He Was the first man who made some attempts on grouping of organisms, he knew only a few kinds of plant and animal and he classified plants and animal by used observation 5- Carolus Linnaeus : He developed principle of the modern Taxonomy and used binominal nomenclature to classified organisms Q3/ How did Aristotle classified organisms 1- He classified plants as (herbs , shrubs and trees) 2- - He grouping animals according to where they lived :( water , land and air ) Q2/ How did Carl von linne classified organisms He classified organisms by used binominal nomenclature: it mean two Latin names for each organism the first is a genus and second is a species Q4/ Give the reason : classification is very necessary because a- biologists estimate that there are about two million kinds of organisms live today on our planet b-new species are continuously being discovered Q5/ numerate the historical stages of classification? 1- Ancient classification 2- modren classification Chapter (1 ) Lecture number(2) Species : is a group of living things which have many common properties.

Most plants cannot use nitrogen directly from the air. Nitrogen fixing bacteria take in nitrogen from the air and change it to a form that plants can use 2- Recycling : It means the dead leaves and twigs are recycled over time with the help of bacteria 3- Cleaning Up: - bacteria and other microorganisms are also used to fight pollution.

Many antibiotics are made by bacteria 5- Bacteria in your food: - people add bacteria for food. Every time you eat cheese, yoghurt, buttermilk , or sour cream , you are also eating bacteria 6- Pathogenic bacteria :- most bacteria are cause many diseases and called as pathogenic bacteria such as.cholera ,tetanus , tuberculosis are some diseases caused by bacteria Preparation of bacteria culture Note: bacteria can easily reproduce in lab conditions.
