7-2 Eukaryotic Cell Structure Objectives Recognize cells both increase in number and differentiate, becoming specialized in structure and function, during and after embryonic development. Describe the structure of cell parts found in different types of cells and the functions they perform. Explain physical and chemical interactions that occur between organelles as they carry out life processes. Can I do This??? Identify and describe cell structures and functions. Define organelles by their functions. You Need a Card Question #1 Which of these is not a part of the cell theory? a. Cells are the basic unit of structure and function for living things. b.

Every cell in your body is exactly the same, no matter what type it is. SMART Response Q T o set the properties right click and select SMAR T Response Question Object->Properti Eukaryotic Cell Analogy Comparing the Cell to a Factory Organelle= “little organ” Found only inside eukaryotic cells! Everything in a cell except the nucleus is cytoplasm. Expert Groups!!! FROM HERE,YOU WILL PRESENT THE INFORMATION FOR NOTES! A – Lysosomes K – Ribosomes Q – Nucleus J – Endoplasmic Reticulum (rough and smooth) 10 – Cell Membrane 9 – Mitochondria 8 – Golgi Apparatus 7 – Cytoplasm/Cytoskeleton 6 – Vacuole 5 – Cell Wall 4 - Chloroplasts Answer in Your Notes!!! 1) 2) 3) What is the organelle’s function? What page and paragraph/section did you find this in? What analogy do your group come up with in order to help remember the function of your organelle? What is at least one other interesting fact about your organelle? When You Are Done Being an Expert Your questions/answers need to be approved by Mr. Cramer. Once they have been approved, you can begin your work on the Animal Cell Coloring WS. 7-2 Eukaryotic Cell Structures Continued… Objectives Recognize cells both increase in number and differentiate, becoming specialized in structure and function, during and after embryonic development. Describe the structure of cell parts found in different types of cells and the functions they perform. Explain physical and chemical interactions that occur between organelles as they carry out life processes. Can I do This??? Identify and describe cell structures and functions. Define organelles by their functions. Nucleus Analogy: “The Control Center” “The Boss” “The Mayor” Function: Contains DNA and controls the cell. DNA is the coded instructions for making proteins. Ribosomes Analogy: “Factory Machines” Function: Site of protein synthesis. Found both on rough ER and throughout the cytoplasm. Endoplasmic Reticulum Analogy: “Highway of the cell” Function: Site where proteins/lipids are assembled and delivered through the cell. Rough ER: studded with ribosomes; it makes proteins Smooth ER: no ribosomes; it makes lipids Golgi Apparatus Analogy: “The Mailroom” “UPS”/ ”Fed-Ex” Function: Modifies, sorts, and packages materials for transport inside/outside the cell. Lysosomes Analogy: Function: “Clean-up Crew” “Janitors” (Custodial Technician) Breakdown materials so the cell can use them. Breakdown useless organelles and dispose of them. Contain strong digestive enzymes. Mitochondria Nickname: “The Powerhouse” Function: Creates energy from the food you eat. Has it’s own strand of DNA. Almost all mitochondria comes from the cytoplasm of the egg cell (all mitochondria came from your mom). Stoppage & Closure Summary Write in complete sentences: In your opinion, what is the most important organelle to the success of the cell, we’ve covered so far, and what is its function. 7-2 Eukaryotic Cell Structures Still Continued… Objectives Recognize cells both increase in number and differentiate, becoming specialized in structure and function, during and after embryonic development. Describe the structure of cell parts found in different types of cells and the functions they perform. Explain physical and chemical interactions that occur between organelles as they carry out life processes. Can I do This??? Identify and describe cell structures and functions. Define organelles by their functions. Cell Membrane Analogy: “Door Man” “Gate” Function: Controls what enters and leaves cell. Thin flexible barrier. Cytoskeleton Analogy: “Steel Beams” Function: Gives cell structure and shape. Network of fibers that run through cytoplasm. Gel substance that makes up cell. Vacuole Analogy: “Storage Container” “Warehouse” Function: Stores materials such as water, salts, proteins, and carbohydrates. Large central vacuole in plant cells. Many smaller vacuoles in animal cells. Cell Wall Analogy: “Walls” Function: Strong supporting layer around membrane that gives cell shape. Only in plant cells. Chloroplasts Analogy: “Solar Panels” Function: Traps energy from the sun to produce food for the plant. Contains the green pigment chlorophyll. Can I do This??? Identify and describe cell structures and functions. Define organelles by their functions. Summary & Closure Any questions for the good of the cause? When are organelle projects due??? Summary on Back What is the purpose of the organelles found only in plant cells? Can I do This??? Describe the path a protein takes as it is manufactured by the cell. I can describe the path of a lipid as it is manufactured by the cell. Some Important Vocabulary Protein – molecule needed by the body for growth, repair, and to create important enzymes. Lipids – molecule used in cell membrane, includes fats and oils. Both are made from elements such as hydrogen, carbon, nitrogen, and oxygen. The Journey of a Protein Using the and the 7-2 notes (it’s the table with all of the organelles), identify which cards are involved the production, transfer, or delivery of a protein. Nucleus Rough ER Lysosomes Golgi Apparatus MitochondSmooth ER ria Ribosomes Released From Cell The Journey of a Protein Path of a Protein: 1. 2. 3. 4. Ribosome Rough ER Golgi Apparatus Export from cell or to the appropriate organelle The Journey of a Lipid Path of a Lipid: 1. 2. 3. Smooth ER Golgi Apparatus Sent for use in cell membrane or other organelles. Closure What is due tomorrow???
