So why do scientists consider bacteria living organisms while viruses are often described as being on the “edge of life”? Why do some things on Earth, like animals and plants, exhibit life, while others, like rocks and water, do not? What sets characteristics that define life itself? Activity: 2 Truths and 1 Lie 5 groups A. Cell biology Create 2 sets of 3 statements with: 2 truths B. Photosynthesis and one lie about the C. Ecology and topic assigned ecosystem 15 minutes D. Evolution Guess which is a lie and E. Nonliving things 2 truths. Example 1. Plants perform photosynthesis to make their own food. 2. Fungi make their own food through photosynthesis. 3. Humans have over 600 muscles in their bodies. Example 1. Plants perform photosynthesis to make their own food. 2.

Humans have over 600 muscles in their bodies. Post your statements here: Individual Task: Ranger360 Access the Claim-Evidence-Reasoning worksheet on Ranger360. Read The Martian and the Car and answer the worksheet. Your task: 1. Act both as the Defense Attorney (defends Marvin who believes that the car is alive) and the Prosecutor (the car is not alive). 2. As the defense attorney: prove Marvin’s claim that the CAR IS ALIVE by providing evidence with reasons. 3. As the prosecutor: explain how Martian’s testimony is wrong– that his observations are flawed. Instead, you will give an actual example of this characteristic of life and use it as evidence against Marvin’s testimony. 4. Fill-up the Claim-Evidence-Reason Worksheet on Ranger360 and submit today. The Martian and the Car During his first mission for the Martian government, Marvin the Martian was sent to Earth by the Martian government to find evidence of life. While on Earth, Marvin captured a car and brought it back to Mars. He thought he'd found a good example of life on Earth. The Martian government does not believe that the car Marvin brought back is alive; therefore, he must stand trial for failing to perform his Martian duties. Supplementary materials Unifying Themes of Biology – Pearson eBook pages 51 to 59 Online sources: https://bio.libretexts.org/Bookshelves/Introductory_and_G eneral_Biology/Book%3A_General_Biology_(Boundless)/01 %3A_The_Study_of_Life/1.07%3A_Themes_and_Concepts_ of_Biology_-_Properties_of_Life As the defense attorney, how can you prove that Marvin’s claim that the CAR IS ALIVE is true? As the prosecutor, how will you explain that Marvin’s claim that the CAR IS ALIVE is not true? If a Martian were to argue that the car is alive, how would you respond? What aspect of life do you think is most convincing? Lesson 1: Introduction to Zoology Essential Questions 1. How are animals different from other organisms? 2. What characteristics do all animals share? 3. How do animals carry out their essential life functions? What is Life? Define LIFE. Introduction GB2 deals with the living world, but what qualifies as “living”? Characteristics or properties that would describe what is ALIVE Recall: What are the characteristics of Living Things? A. FUNDAMENTAL PROPERTIES OF LIFE 1. Chemical Uniqueness Assemblage of complex, large molecules called MACROMOLECULES Though same atoms and bonds in non-living they still obey the fundamental laws of chemistry. Their COMPLEXITY is what makes them UNIQUE FORMS FIT FUNCTION! Recall: What are the 4 major macromolecules in living organisms? 2. Complexity and Hierarchical Organization NON-LIVING = atoms → molecules → crystals What about the biological organization order in living organisms? 2. Complexity and Hierarchical Organization At what biological order would social behavior appear? A. CELLULAR B. ORGANISM C. POPULATION D. TISSUE  CELLS Smallest functional unit of life “SEMIAUTONOMOUS” 3. Reproduction Life does not arise spontaneously Cellular level = cell division Organism level = sexual/asexual Reproduction is both contrary and complementary HEREDITY - transmission of traits VARIATION – production of different and unique traits BOTH ARE ABSOLUTELY NECESSARY! What will happen if HEREDITY is PERFECT? No genetic diversity No evolution No environmental adaptation High risk of extinction What will happen if VARIATION is UNCONTROLLED? Unstable population Rapid growth of new species More genetic diversity Ecosystem impacts Genetic disorders and diseases  4. Possession of a Genetic Program Molecule of inheritance: nucleic acids → encodes the structure of the protein → dictate the development and function of the organism. What do you call the repeating structure/unit of nucleic acids? Nucleotide  RECALL: Which part of the DNA is responsible for the genetic code of the amino acids (in the protein) Genetic code (used in determining the sequence of amino acids)  More ideas about DNA From bacteria to higher form of organisms like human, they share the same genetic code. Proof of single origin of life 5. Metabolism and Homeostasis Maintenance of the body is achieved through acquiring nutrients. Chemical energy + molecular components for building Digestion Synthesis of Acquire molecules/structures energy  5. Metabolism Maintenance of the body is achieved through acquiring nutrients. Happens at the cellular level GOAL: Maintain a stable state - HOMEOSTASIS Where does cell respiration takes place? Mitochondria – TCA Cytoplasm - glycolysis 6. Development 6. Development Refers to the process by which an organism matures and changes over time. Differentiation and specialization of cells, tissues, organs → formation of more complex structures and functions. Guided by genetic information and environmental influences. Can happen in different life stages.  6. Development UNICELLULAR – size, replication of parts (until it divides) MULTICELLULAR – differentiation of cells and parts, complex structures, life cycles 7. Environmental Interaction Animals respond to changes in the environment Environment interaction rangers from: Simple – unicellular move towards light or away from toxins Complex – mating call Background gif is an example of mating ritual of Superb Bird of Paradise 8. Movement Ability of an organism to change its position or location. Voluntary or involuntary Can occur at various levels – cellular to organismal/population 1. Cellular level – movement of molecules, response to signals 2. Organism level – muscle movement (walking, swimming, flying), tropism in plants 3. Population level – changing geographical location (immigration) 8. Movement Purpose of movement: 1. Survival 2. Enabling interactions between organisms 3. Reproduction 4. Influence population dynamics and community structure 5. Homeostasis
