1 THE CELL model: Activity 4.1 Science / Biology Objective: On a team of no more than (2). Build to illustrate a 3D model of a PLANT or ANIMAL cell. - Your models should clearly demonstrate the following expectations from the rubric below. Knowledge: What you need to know to complete this task. (1) Explain the specific function of organelles inside the cell. (2) Identify an organelle by its location/exterior appearance. (3) Analyze/explain how functions of the cells organelles maintain equilibrium within the cell. Scoring Rubric Category Description Points/Earned The model Organelles / Information Oral-Presentation The group has creatively constructed a 3-dimensional model of a cell (plant or animal) Using your in class organelle sheet, all organelles must be clearly visible and labeled. Labels should include the correctly spelled NAME placed in its proper location Colors of structures are non-specific, but should display contrast between other parts of the cell. Student/Groups will orally present their models. These presentations will include - Explanation of model parts (materials used) - Answering questions about organelle placement and function 10 pts. **Models must be constructed of throwaway items. Purchased models or items purchased for the purpose of model building will receive lower scores Creativity is an expectation of this assignment 14 x 5-70 pts. (Animal Cell) 14 x 5 70 pts. (Plant Cell) Contrast indicates organelles that have different functions should have different colors Oral Presentation + Each question x 5 Pts. 20 pts. Plant Cell 4 Questions 20 pts.

3 ORGANELLE In Plant? In animal? STRUCTURE & FUNCTION Cell membrane (Plasma membrane) Boundary between inside and outside environment of cell. Regulates entry/exit of substances. Cell wall No Rigid structure providing support for cell. Cytoplasm Cyto-skeleton Jelly-like substance filling intracellular space, gives cell volume. Network of fine tubes and threads. Provides internal structural support. Centrioles No Paired rods, which help organize mitosis. Nucleus Nucleolus Nuclear Membrane Mitochondria Chloroplasts Photosynthesis Single-Large No Ribosomes (ER) -smooth (ER) -rough Golgi Apparatus (Golgi Body) Multi-Small Lysosomes Membrane-bound structure containing cells' genetic information (DNA) Small structure within nucleus. Site of production of ribosomes. Boundary between nucleus and cytoplasm. Regulates passage of materials in and out of the nucleus Membrane bound organelles. Folded membranes contain enzymes for aerobic respiration, which make energy. Membrane bound organelles. Folded membranes within contain chlorophyll and enzymes for photosynthesis. (A little DNA in here too.) Membrane bound area filled with water and assorted solutes. Role in maintenance of water balance of the cell. Small organelles at which protein synthesis occurs. May be free floating or membrane-bound. Network of flattened membranes forming tunnels. Enzymes assisting synthesis of some lipids and final processing of proteins found here. Similar to smooth ER, but with ribosomes embedded in membrane. Proteins to be exported from cell produced here. Stacks of saucer shaped membranes where export proteins are modified and stored prior to entering vesicles. Membrane bound structure-containing enzymes, which break down toxic or unwanted molecules. Vesicles No Packages for storage or temporary transport

7 Cell Organelles Structure & Functions Test 1-14 Read each description and select the correct organelle from the list on the board. Do not spell out the organelle name. You need only put the letter without spaces, capitalization is not important. The diagram that has been provided can be used to assist you. 1. Which organelle is referred to as the control center and contains the genetic material necessary for replication/division? (5 pts.) 2. Which organelle is responsible for making proteins? (A protein factory) (5 pts.) 3. Which organelle acts as a temporary transport system, using vesicles to move proteins and lipids throughout the cell? (5 pts.) 4. Which organelle is known as the power-house or power plant using respiration to make energy for the cell? (5 pts.) 5. Which organelle acts as the garbage man of the cell using enzymes to break down toxins, waste and unwanted materials? (5 pts.) 6. Which organelle is a rigid structure that provides support and can only be found in a plant cell? (5 pts.) 7. Which organelle is the cells storage center where you can find food, water and waste? (5 pts.) 8. Which organelle is responsible for producing ribosomes and has a name similar to another organelle found in both plant and animal cells? (5 pts.) 9. Which organelle found only in the animal cell is responsible for the organization of cell division? (5 pts.) 10. Which organelle is a fixed transport system that does not have the ability to make proteins? (5 pts.) 11. **Bonus: What is the jelly-like substance that fills both the plant & animal cell, creating space for the other organelles and giving the cell volume? (+5 pts.)
