Obtain, evaluate, and communicate information to analyze the nature of the relationships between structures and functions in living cells.Construct an explanation of how cell structures and organelles (including nucleus, cytoplasm, cell membrane, cell wall, chloroplasts, lysosome, Golgi, endoplasmic reticulum, vacuoles, ribosomes, and mitochondria) interact as a system to maintain homeostasisd. Plan and carry out investigations to determine the role of cellular transport (e.g., active, passive, and osmosis) in maintaining homeostasis.Disciplinary Core Ideas: LS1: From Molecules to Organisms: Structures and ProcessesFocus on “Science & Engineering Practices”:Asking Questions and Defining problemsDeveloping and using models.Planning and carrying out investigationsAnalyzing and interpreting dataUsing Math and computational thinkingConstructing explanations and designing solutionsEngaging in argument from evidenceObtaining, evaluating, and communicating informationGuiding Question(s):What are the two main groups cells are classified?How do cells contribute to the function of living organisms?How do organisms maintain a biological balance between their internal and external environments?How does the structure of an organelle allow the organelle to perform its job?Assessment Evidence:Formative Assessments (observations, prompts, dialogues, practice, etc.):Cell Organelle QuizTransport QuizVocabulary QuizPerformance Task(s):Cells ILPProkaryote vs Eukaryote LabPlant vs Animal Cell MysteryTransport labSummative Assessment: Cell Organelle and Cellular Transport TestQuizlet Vocabulary List: Cell Organelle - A specialized subunit within a cell that has a specific function, and is usually separately enclosed within its own membraneCell membrane (plasma membrane) - The thin layer of protein and fat that surrounds the cell. The cell membrane is semipermeable, allowing some substances to pass into the cell and blocking others. Cytoplasm - The jellylike material outside the cell nucleus in which the organelles are located.Mitochondrion - Spherical to rod-shaped organelles with a double membrane. The mitochondrion converts the energy stored in glucose into ATP (adenosine triphosphate) for the cell.Golgi apparatus - A flattened, layered, sac-like organelle that looks like a stack of pancakes and is located near the nucleus. The Golgi body packages proteins and carbohydrates into membrane-bound vesicles for "export" from the cell.Lysosome - Spherical organelles surrounded by a membrane; they contain digestive enzymes. This is where the digestion of cell nutrients takes place.Nuclear membrane - The membrane that surrounds the nucleus.Nucleus - The nucleus controls many of the functions of the cell (by controlling protein synthesis) and contains DNA (in chromosomes). The nucleus is surrounded by the nuclear membrane.Nucleolus - An organelle within the nucleus - it is where ribosomal RNA is produced. Some cells have more than one nucleolus.Chromosome - One of the tiny, threadlike, DNA-containing bodies found in the cell nuclei of all plants and animals, responsible for transmitting hereditary characteristics.Ribosome - Small organelles composed of RNA-rich cytoplasmic granules that are sites of protein synthesis.Rough endoplasmic reticulum (rough ER) - A vast system of interconnected, membranous, in-folded and convoluted sacks that are located in the cell's cytoplasm (the ER is continuous with the outer nuclear membrane). Rough ER is covered with ribosomes that give it a rough appearance. Rough ER transports materials through the cell and produces proteins in sacks (which are sent to the Golgi body, or inserted into the cell membrane).Smooth endoplasmic reticulum (smooth ER) - Smooth ER transports materials through the cell. It contains enzymes and produces and digests lipids (fats) and membrane proteins; smooth ER buds off from rough ER, moving the newly-made proteins and lipids to the Golgi body, lysosomes, and membranes.Vacuole (animal) - Fluid-filled, membrane-surrounded cavities inside a cell. The vacuole fills with food being digested and waste material that is on its way out of the cell.Vacuole (plant) - A large, membrane-bound space within a plant cell that is filled with fluid. Most plant cells have a single vacuole that takes up much of the cell. It helps maintain the shape of the cell.Cell wall (plant) - A thick, rigid membrane that surrounds a plant cell. This layer of cellulose fiber gives the cell most of its support and structure. The cell wall also bonds with other cell walls to form the structure of the plant.Chlorophyll (plant) - The green pigment in the leaves and stems of plants that is necessary for the production of plant food by photosynthesisChloroplast (plant) - An elongated or disc-shaped organelle containing chlorophyll. Photosynthesis (in which energy from sunlight is converted into chemical energy - food) takes place in the chloroplasts.Eukaryote - Any of the single-celled or multicellular organisms whose cell contains a distinct, membrane-bound nucleus.Prokaryote - Any of the group of organisms primarily characterized by the lack of true nucleus and other membrane-bound cell compartments: such as mitochondria and chloroplasts, and by the possession of a single loop of stable chromosomal DNA in the nucleoid region and cytoplasmic structures, such as plasma membrane, vacuoles, primitive cytoskeleton, and ribosomes.Flagellum - a slender threadlike structure, especially a microscopic whip-like appendage that enables many unicellular organisms to swim.Cilia - a short, microscopic, hair-like vibrating structure.Hydrophilic - Having an affinity for water; capable of interacting with waterHydrophobic - Lacking an affinity for water; insoluble in water; repelling water.Osmosis - Diffusion of a solvent (usually water molecules) through a semipermeable membrane from an area of low solute concentration to an area of high solute concentration.Diffusion - The passive movement of molecules or particles along a concentration gradient, or from regions of higher to regions of lower concentration.Facilitated diffusion - Transport of substances across a biological membrane from an area of higher concentration to an area of lower concentration by means of a carrier molecule. Since the substances move along the direction of their concentration gradients, energy is not required.Active Transport - A kind of transport wherein ions or molecules move against a concentration gradient, which means movement in the direction opposite that of diffusion – or – movement from an area of lower concentration to an area of higher concentration. Hence, this process will require expenditure of energy, and the assistance of a type of protein called a carrier protein.Passive Transport - A kind of transport by which ions or molecules move along a concentration gradient, which means movement from an area of higher concentration to an area of lower concentration.Selectively Permeable - A feature and a function of the plasma membrane that is essential to maintain homeostasis by regulating the passage of some substances while preventing others from entering the cell.Isotonic - Having equal tension or tonicityHypotonic - a solution with a comparatively lower concentration of solutes relative to the amount of solutes in another solution or a solution being compared with has less osmotic pressure in a fluid compared to another fluid.Hypertonic - a solution with a comparatively greater solute concentration than that in another solution or a solution being compared with has greater osmotic pressure in a fluid than the other fluidLearning Plan: Check BoxDateCW/HWInstructional FocusF Sept. 1Cell organelles Checklist 1 Prokaryote vs Eukaryote POGILM Sept. 4Labor Day HolidayT Sept. 5Cell organelles Checklist 2 Cell organelles chart3 Plant and Animal Cell labeling and coloringHWFinish Checklist items before labW Sept. 6179006566675Prokaryote vs EukaryotesPlant vs Animal Cell Mystery Microscope LabTh Sept. 7Organelle VideoFinish Lab Analysis QuestionsF Sept. 8Cell Membrane Interactive Reader Summarizing AssignmentM Sept. 11Cell Transport NotesActive and Passive Transport WorksheetHWActive and Passive Transport WorksheetT Sept. 12Prokaryote vs Eukaryote, Cell Organelles QUIZCell Transport Video SeriesCell Transport NotesW Sept. 13Cell Transport Video SeriesCell Transport Review PacketTh Sept. 14Active Transport Scribble NotesPacket WorkF Sept 15Cell Organelles and Cell Transport ReviewM Sept 18 Cell Organelles and Cell Transport TESTMark your level of understanding after each activity: A: I am able to do this B: I am BEGINNING to get thisC: I still CAN’T do this A B C I can provide evidence that organisms are made of a single cell or many cells.
