4.02 Hierarchical Structure.notebook February 06, 2022 Unit 4: How to maintain a stable existence? 4.02 Hierarchy Learning objectives Guiding questions 1) Students will understand that functions of What are the hierarchical parts that make up a multicellular organism? biological systems rely on the emergent properties How does hierarchical structure enable specialization at the molecular that develop from the hierarchical structure within an organism. What are the main elements that biological macromolecules (proteins, carbohydrates, fats) are made of? 2) Living organisms recombine a few elements to How does an organism (animal) acquire these elements? form building blocks and support life by transferring What is special about carbon’s structure, that makes it the most basic element matter and energy © that living organisms are made of? Starter: 3 parent‐babies Key words: Yes, it's now a thing! hierarchy, hierarchical Watch the video on the next slide to learn more structure, emergent properties, macromolecule, organelle, cell tissue, organ, organ system 4.02 Hierarchical Structure.notebook February 06, 2022 Thinking point: How does 1 molecule have such a large impact on the structure of a person? Key take away: Organisms have a HIERARCHY in their structure that allows different parts to work together like building blocks. 4.02 Hierarchical Structure.notebook February 06, 2022 Hierarchy­ a system in which members of an organization or society are ranked accoring to relative status or authority Organistational Hierarchy complex job simple jobs Systems diagram for the structure of an organisation "The sum of the parts" All these little components together lead to "Emergent Properties" from the system. These are properties that only exist because all the little pieces work together. e.g. alone, these people cannot develop a new fusion powerplant ­ but together.....BOOM!! 4.02 Hierarchical Structure.notebook February 06, 2022 Systems working together Everything is connected Using the white­boards as a background, arrange the cards your teacher gives you into a heirarchical structure that you agree with. On the white board, draw connections between the components and discuss as a group. Atom Atom Atom Atom Atom Atom Atom What are emergent properties organisms have? Which ones can relate to your model? Extension: Your teacher may instruct you to walk around and explore another group's model. 4.02 Hierarchical Structure.notebook February 06, 2022 Generally accepted hierarchical structure of living organsims This model excludes non­living components Hierarchy (in order of rank) Specific example This and other systems, each with different functions, WORK TOGETHER to keep an organism functioning. 4.02 Hierarchical Structure.notebook February 06, 2022 How do parts of your system work together? WONDER: Select 3 organs from your word sort and discuss how they work together to keep you functioning. INFER: Arrange the 3 selected organs into a mini­system and draw annotated arrows to show how they work together to support a functioning system aka. your body.

Let's go back to this size TO BIG & COMPLEX! 4.02 Hierarchical Structure.notebook February 06, 2022 We boil down to mostly just 4 atoms! Carbon, hydrogen, oxygen & nitrogen (CHON) are the main atoms that form ALL living organisms. What is special about the structure of carbon, that makes it the most basic element that living organisms are made of? drag for answer 4.02 Hierarchical Structure.notebook February 06, 2022 MACROMOLECULES Atoms bond together in predictable ways to form the building blocks of life e.g. atoms (CHON)...small molecule (amino acid, sugar, fatty acid)....macro molecule (protein, carbohydrate, fat, nucleic acids)...... 4.02 Hierarchical Structure.notebook February 06, 2022 You are what you eat! CHON make up our macromolecules macro means _______________ Protein CHON ­­> Amino Acid ­­­> Protein ­­­> muscle, hair Carbon, hydrogen, Lipids (Fats) oxygen & nitrogen Carbohydrates DNA (sugars) CHO ­­> simple carbs­­­> complex carbs­­>cell organelle (cell wall in plants) CHO ­­> fatty acids ­­­> fat Carbon, hydrogen, oxygen & nitrogen (CHON) are the main atoms that form our FUEL 4.02 Hierarchical Structure.notebook February 06, 2022 Recombining atoms to make many molecules ­ very versatile, but can we live on candy alone? Biological molecule Why do these atoms make these many covalent bonds? C ­ 4 bonds H ­ 1 bond O ­ 2 bonds N ­ 3 bonds (each kit needs, 2N, 6Cs, 6Os, 12Hs & 25 bonds) Carbohydrate ­ Glucose > With a partner construct a glucose molecule using the atoms provided in your molecular kit > Take a picture of your glucose molecule BEFORE moving to the next step. 4.02 Hierarchical Structure.notebook February 06, 2022 NEXT STEP: Recombining atoms to make proteins from glucose! ­ CAN IT REALLY BE DONE? Amino acid ­ Alanine Amino acid ­ Glutamine > Select ONE of the amino acids from above. Using only the atoms from your glucose molecule, make your selected amino acid? > What do you need to complete your molecule? (AN N NA?) > Once all groups have built an amino acid, line them all up to make a protein! Amino acids are building blocks of proteins.....which is one of the building blocks of a cell, which is a building block of a tissue.....and so on! 4.02 Hierarchical Structure.notebook February 06, 2022 Plenary: Which building blocks of life did we cover today?
