  2. 3.1.LIVING ORGANISMS WHAT IS A LIVING THING? • 1) All the organisms in the biosphere are able to perform three vital functions: • Nutrition, • Interaction, and • Reproduction Here in you can find more characteristics of the living organisms. Make a list and resume all of them in a few words in your notebook http://www.schoolsnet.com/pls/hot_school/sn_lessons.page_pls_lesson_detail?x=16180339&p_lesson_id=88&p_res_type_id=15

  3. 3.1.LIVING ORGANISMS WHAT IS A LIVING THING? • 1) The three vital functions:There are two kinds of nutrition: • AUTOTROPHIC AND HETEROTROPHIC Autotrophs produce their own food by taking water, CO2 and mineral substances from the environment Heterotrophs obtain their food by eating other organisms or their remains

  4. 3.1.LIVING ORGANISMS AUTOTROPHIC NUTRITION Autotrophs produce their own food by taking water, CO2 and mineral substances from the environment Photosynthesis

  5. 3.1.LIVING ORGANISMS HETEROTROPHIC NUTRITION Heterotrophs obtain their food by eating other organisms or their remains Cellular respiration

  6. 3.1.LIVING ORGANISMS Autotrophs and heterotrophs are closely related each others In the film “The Lion King”Mufasa explains to his son Simba how all living things are connected: “Antelopes eat the grass, lions eat antelopes, but when the lions die, their bodies become food for the grass, and so the ‘circle of life’ goes on….” “The Lion King” and its associated characters are the property of Walt Disney Pictures, Incorporated.

  7. 3.1.LIVING ORGANISMS WHAT IS A LIVING THING? • 1) All the organisms in the biosphere are able to perform three vital functions: • Interaction: Living organisms are able to sense changes in their environment and react in order to survive http://www.clam-arte.com.ar/pintor.gif

  8. 3.1.LIVING ORGANISMS WHAT IS A LIVING THING? • 1) All the organisms in the biosphere are able to perform three vital functions: • Interaction: Living organisms are able to sense changes in their environment and react in order to survive Plants grow towards the light Animals detect food and move towards it http://www.youtube.com/watch?v=yps7pgq1TAk&feature=fvsr http://www.youtube.com/watch?v=Ze8NV7cvW8k

  9. 3.1.LIVING ORGANISMS WHAT IS A LIVING THING? • 1) All the organisms in the biosphere are able to perform three vital functions: • Reproduction: Organisms produce descendantsthat maintain their characteristics

  10. 3.1.LIVING ORGANISMS WHAT IS A LIVING THING? 1) Reproduction can be … Sexual Asexual http://www.youtube.com/watch?v=gEwzDydciWc&feature=related

  11. 3.1.LIVING ORGANISMS WHAT IS A LIVING THING? 2) All the living beings in the biosphere are made up of similar substances

  12. 3.1.LIVING ORGANISMS WHAT IS A LIVING THING? 2) All the living beings in the biosphere are made up of similar substances Water (65-90 %)

  13. CARBOHIDRATES LIPIDS PROTEINS NUCLEIC ACIDS 3.1.LIVING ORGANISMS WHAT IS A LIVING THING? 2) All the living beings in the biosphere are made up of similar substances Water (65-90 %) Substances rich in carbon (10-30 %)

  14. 3.1.LIVING ORGANISMS WHAT IS A LIVING THING? 2) All the living beings in the biosphere are made up of similar substances Water (65-90 %) Substances rich in carbon (10-30 %) Mineral substances (1-5 %)

  15. 3.1.LIVING ORGANISMS WHAT IS A LIVING THING? 3) All the living beings in the biosphere are formed by cells A cell is the smallest unit of a living thing capable of performing the three vital functions: nutrition, relation, and reproduction. http://www.youtube.com/watch?v=hOLAGYmUQV0
