335 Characteristics of a Living Thing -Expanded Details Organized Structure - cells & their organelles - DNA/genetic codesGrow and Develop – making new cells, repair of cellsRespond to Environment – adapts, reacts to stimuliReproduction – producing offspringUses/needs energy – photosynthesis & cellular respiration
34ReviewThe two main processes for creating energy in a cell are Photosynthesis & Cellular Respiration but there are many more processes that ensure cell function & survival!
35(Metabolic) Cellular Processes: The processes we will discuss…STERNGRR Synthesis (photosynthesis would fit here)TransportExcretionRegulationNutritionGrowthRespiration (cellular respiration would fit here)Reproduction
36Synthesis How organisms build necessary materials Examples: Protein Synthesis: making proteinsPhotosynthesis: plants make food using energy from sunlight
37SynthesisWhich organelles would mainly be involved in these processes?
38TransportHow organisms get what they need to cells (moving materials within the organism)Examples:Active Transport vs. Passive Transport
39TransportWhich organelles would mainly be involved in these processes?
40ExcretionHow organisms get rid/break down their waste and balance their fluidsExamples:Removing anything unnecessary from the cell
41ExcretionWhich organelles would mainly be involved in these processes?
42Sweating – reduces body temperature RegulationHow organisms control body processesExamples:Important to homeostasis - to maintain balance within the body and adapt to changesSweating – reduces body temperature
43Sweating – reduces body temperature RegulationWhich organelles would mainly be involved in these processes?Sweating – reduces body temperature
44Nutrition How organisms get or obtain food Examples: Fungi decompose dead remains (decomposer)Plants make their own food (autotroph)Animals consume other organisms and absorb food (heterotroph)
45NutritionWhich organelles would mainly be involved in these processes?
46GrowthHow organisms make new cells and develop and repair necessary body partsExample: Cell division (Mitosis)Develop – to change due to hormonal or mental cuesGrow – to get larger in size; body size
47Growth Grow – to get larger in size; body size Which organelles would mainly be involved in these processes?Develop – to change due to hormonal or mental cuesGrow – to get larger in size; body size
48RespirationHow organisms make usable energyExample:
49RespirationWhich organelles would mainly be involved in these processes?Example:
50Reproduction Organisms produce offspring to prevent extinction Examples:Mitosis & MeiosisSexual or Asexual Reproduction
51ReproductionWhich organelles would mainly be involved in these processes?
52A Gummy SituationWe are going to use your gummy bear to demonstrate some of the cellular processes and vocabulary next class.Name your gummy bear, and write the name on the masking tape.Fill your container with water – enough to cover a gummy bear, but not so much that it will spill out when you place the bear in!Put your bear in the water filled container, put the lid on, and put the masking tape label over the lid.
53Part 1: Create a Hypothesis… If I leave my gummy bear baby in water until Friday, then…..because…..
54Relationship Sets – “Self Vocab Quiz” You will create 10 “relationship sets” or sentences to show that you understand the relationship between the vocabulary words from the last 3 lessons.Minimum of 2 words per sentence, but no maximum.You may repeat words, but be careful not to write the same concept over and over.
55Relationship Sets – “Self Vocab Quiz” Bueno (Good): Cellular respiration is the process through which animal cells create energy, and the main organelle involved in this process is the mitochondria.No Bueno (No Good): Organisms can be both biotic or abiotic because they are made of cells.
56Warm-Up: Write your homework – get it stamped! Put your Cell Analogies in the basket!If you did not turn your relationship sets in last class, please turn those in as well!DateSession#ActivityPage2/6 & 2/74Cellular Processes – In Depth7
57Cellular Processes Cellular processes are things needed to keep the cell alive. 1. Photosynthesis2. Cellular Respiration3. TransportActivePassiveDiffusionOsmosis4. Mitosis
581. PhotosynthesisPlant cells use energy from the sun, carbon dioxide and water to make food.ReactantsProcessProductsCarbon DioxideWaterEnergy (sunlight)The chloroplasts take the sunlight, carbon dioxide and water to make foodSugars (glucose)Oxygen
59Chemical Formula for Photosynthesis 6CO2 + 6H2O + Energy from Sunlight ---> 6O2 + C6H12O6STOP & THINK:Is this endothermic or exothermic?
602. Cellular RespirationAnimal Cells then use the oxygen and sugars to “breathe” and make energy (ATP)ReactantsProcessProductsSugars (glucose)OxygenThe mitochondria takes the sugar and the oxygen and makes energyCarbon DioxideWaterEnergy (ATP)
61Chemical Formula for Cellular Respiration C6H12O6 + 6O2 → 6CO2 + 6H2O + EnergySTOP & THINK:Is this endothermic or exothermic?
62Turn & Talk: Cellular Respiration Question Why do you breathe more when you’re running around than when you’re sitting watching television?
63Cellular Respiration Answer Because you’re requiring more energy when you run than when you’re just sitting watching TV right?So if you need more energy, then you need more oxygen to give you that energy so your cells undergo respiration!
643. TRANSPORT Things have to move in and out of the cell There are 2 types of transportActive TransportPassive TransportRemember: Which organelle allows things to enter or leave the cell?
65Materials are moved in and out of cell using the cell’s energy Active VS. PassiveMaterials are moved in and out of cell using the cell’s energyMaterials are moved in and out of cell WITHOUT using the cell’s energyRemember:Which organelle makes the energy for the cell again?What is that process called when the cell makes energy?
66Passive TransportThe cell uses 2 main processes to passively move materials in and out of the cell.DiffusionOsmosis
67Diffusion BUT WHY?? Process by which molecules spread out Move from areas of HIGH concentration to LOW concentrationBUT WHY??
68EquilibriumMolecules don’t like to be crowded, so they spread out, or diffuse, until their concentration is equal everywhere, which is called equilibrium.
69Turn & Talk: Diffusion Questions What happens when you add Kool-Aid to water?What happens when you keep adding water?
70Diffusion Review Answer The Kool-Aid begins to diffuse throughout the water until the Kool-Aid reaches equilibrium.The Kool-Aid becomes less concentrated (both the color and the flavor) as you add more water.
72Osmosis The diffusion of water through a membrane Remember: Which organelle would store water in the cell??Which organelle would the water have to pass through to enter the cell again?
73Turn & Talk: Osmosis Question Why do your hands get wrinkly when you’re in the water for a long time?
74Osmosis Review AnswerWhen your hands are in water for a long period time you wash off the oily substance that keeps water from entering your skin. So once that oily layer is washed away your skin becomes semi-permeable and water passes through the membrane, which is osmosis. Your hands become wrinkly because they are trying to reach equilibrium with the water, but only some of your skin is actually attached to the tissue underneath!!Bonus – it is an evolutionary adaptation that helps us grip wet objects!
76Let’s take a break and check on our Gummy Bear Babies… Using the following vocabulary words, explain what happened to your baby:Transport (distinguish whether it is active or passive)OsmosisDiffusion/DiffuseConcentrationEquilibrium
774. MitosisThe steps a cell goes through to reproduce and make more cells so an organism can grow and repair itselfNew cell is an exact copy of original cell
78Mitosis Mitosis is a process broken down into 4 parts: Part 1: ProphasePart 2: MetaphasePart 3: AnaphasePart 4: Telophase
79MitosisUse your book to fill out the graphic organizer for Mitosis…Pages E82-E83ProphaseNuclear membrane disappearsDNA condenses into chromosomes
80Mitosis Metaphase Chromosomes line up in the middle of the cell Chromosomes split into two identical separate setsThe 2 sets of chromosomes pull to the opposite ends of the cellAnaphase
81Mitosis Telophase 2 new nuclear membranes form The cell pinches and divides into 2 new cells!!cytoplasm is divided which is called cytokinesis
82Mitosis & Binary Fission Why do you think it is important for the DNA/chromosomes to be copied before the cell divides?What is binary fission? How is it similar and different to mitosis?
84Tie it all Together…For the cells to carry out all of these processes, what do they need?How do we get that energy?Do all foods give us the same nutrients and therefore amount of energy?So, how do we ensure that our cells stay healthy and are able to function?
85HOMEWORKBring in a nutrition label from any food next class…feel free to bring extras for those who “forget!”BYOT
