  1. LESSON 27: Cell Structures Life Science

  2. Lesson 27 – Cell Structures • Click here to view an animation on cell structures & functions. • Review the vocabulary in this lesson. • OGT Skills Checklist - At the end of this lesson, you should be able to answer the following questions: • What is the difference between prokaryotes and eukaryotes? • What cell structures make up a cell and what are their functions? • What are the differences between plant and animal cells?

  3. Nucleus DNA RNA Cell Membrane/ Plasma Membrane Cytoplasm Mitochondria Golgi Apparatus Ribosome Endoplasmic Reticulum Vacuole Flagellum Cilia Cell Structures – Vocab Review

  4. Nucleus • Part of the cell that contains DNA & RNA. • Controls cell’s growth & reproduction.

  5. DNA • Deoxyribonucleic acid. • Contains the instructions needed to make proteins that perform important functions for an organism (examples: develop, survive and reproduce). (Image from http://files.turbosquid.com/Preview/Content_on_2_26_2005_13_38_09/DNA8-400.jpg71abe163-6969-448a-8c20-b7209efeefb0Large.jpg)

  6. RNA • Ribonucleic acid. • Carries the genetic instructions from DNA in nucleus to cytoplasm where proteins are made. (Image from http://www.biologycorner.com/resources/mRNA-colored.gif )

  7. Cell Membrane(Plasma Membrane) • Surrounds the cell. • Controls what can come into or leave the cell. (Image from http://medicineagency.com/blog/wp-content/uploads/2008/04/bouncer_big.JPG) (Image adapted from http://4.bp.blogspot.com/_X06sfPDLGS8/RbitsNpRurI/AAAAAAAAABU/nJTZow03j0c/s320/Animal-cell.gif)

  8. Cytoplasm • Fluid that fills the cell. (Image from http://s3.amazonaws.com/alpha.spongefish.com/329/wide/jlo123_stvs_spins_fruit_bowl.jpg) (Image adapted from http://4.bp.blogspot.com/_X06sfPDLGS8/RbitsNpRurI/AAAAAAAAABU/nJTZow03j0c/s320/Animal-cell.gif)

  9. Mitochondria • Provides cell with energy. (Image from http://pro.corbis.com/images/CB064937.jpg?size=572&uid=%7BD6ECB545-940A-4C61-A68D-5CA2A591862E%7D) (Image adapted from http://4.bp.blogspot.com/_X06sfPDLGS8/RbitsNpRurI/AAAAAAAAABU/nJTZow03j0c/s320/Animal-cell.gif)

  10. Golgi Apparatus • Membrane bound organelle that packages and secretes (releases) products. (Image from http://school.discoveryeducation.com/clipart/images/package.gif ) (Image adapted from http://4.bp.blogspot.com/_X06sfPDLGS8/RbitsNpRurI/AAAAAAAAABU/nJTZow03j0c/s320/Animal-cell.gif)

  11. Ribosome • Functions to make proteins based on DNA instructions. (Image from http://cheezeworld.com/object-creation-game-factory/) (Image adapted from http://4.bp.blogspot.com/_X06sfPDLGS8/RbitsNpRurI/AAAAAAAAABU/nJTZow03j0c/s320/Animal-cell.gif)

  12. Endoplasmic Reticulum • A membrane network used for transport within the cell. (Image adapted from http://4.bp.blogspot.com/_X06sfPDLGS8/RbitsNpRurI/AAAAAAAAABU/nJTZow03j0c/s320/Animal-cell.gif)

  13. Vacuole • Membrane bound organelle that contains fluid. Can be used for storage. (Image from http://www.usoe.k12.ut.us/curr/Science/sciber00/7th/cells/images/vacuole.gif)

  14. Other Parts: Flagellum • Long projection that is used to help the cell move (locomotion) • Only found in some cell types (Image from http://www.kaskaskia.edu/BCambron/Biology%20101%20Chapter%204_files/image002.jpg)

  15. Other Parts: Cilia • Many short, thin projections that can be used to help the cell move (locomotion) • Only found in some cell types (Images adapted from http://www.occc.edu/biologylabs/Documents/Animals_2/Ciliates.htm)
