Organelles Day 3 Objective: SWBAT describe the structure and function of organelles related to protein Catalyst: What is the function of the organelle which the arrow is pointing to? Agenda Catalyst Review Quiz 4 more invites to the cell-ebration Practice Coloring! Exit Question Ribosome Ribosomes are very small circles that are sometimes on the Endoplasmic Reticulum and sometimes floating in the cytoplasm They make protein (which the cell uses to do all cell activities) Analogy: Teachers Ribosomes Endoplasmic Reticulum Re-tick-you-lum These are tubes that are always around the nucleus. -Smooth ER: no ribosomes -Rough ER- ribosomes -It is a passageway for proteins. Analogy: Hallways of West Jeff Endoplasmic Reticulum Golgi Apparatus It is many flattened sacs put together It packages and ships out proteins Analogy: Attendance Office- ships people around Golgi Apparatus Golgi Apparatus Lysosome Spherical vesicles Assists with digestion and breaking down oldorganelles Think “Clean-up crew” Analogy: Custodians It’s Time for…. Fill out your sheets with the words in the word bank! Control center of the cell; cell’s brain Manufactures protein. Controls what enters and leaves of the cell Clean-up crew of the cell. This type of cell has DNA floating in the middle of the cell. Looks like spaghetti. Only in plant cells. Allows for photosynthesis to occur. Only in plant cells. Outside the cell membrane. Gives the plants a rectangular shape. Power house of the cell. Creates ATP. Storage for food and water. HUGE in plants. This is a type of endoplasmic reticulum WITH ribosomes. These are tubes found around the nucleus. All organelles float in this liquid substance. In ALL cells. This type of cell has membrane bound organelles, including a nucleus. Packages and modifies protein. This is found in the nucleus. Instructions for all cells. This is usually the shape of plant cells. The ribosome creates this. The cell uses this to carry out its functions. This type of cell has a cell wall, chloroplasts, and a huge vacuole. Also, its usually rectangular. This is a type of endoplasmic reticulum WITHOUT ribosomes. This is a eukaryotic cell that is not rectangular and has no cell wall. Closing Each organelle has a specific purpose that allows the cell to function. To be inducted into the biology club, you need to know all the organelles. Exit Question What is the difference between rough ER and smooth ER? What happens in the ribosome?
