Cell Organellesorganelle = tiny organ

If you think of a cell like a city, each organelle would be a building; with its own structure and job to do.

nucleus
NUCLEUS
  • Description of Structure
    • Spherical body usually near the center of a cell
  • Function of Structure
    • Controls all cells activities
    • Directs Growth and Reproduction
    • Control Center
  • City Hall
nuclear membrane
NUCLEAR MEMBRANE
  • Description of Structure
    • Thin, two layered (porous) structure surrounding nucleus
  • Function of Structure
    • Controls movement of materials in and out of nucleus
    • “Nuclear Gatekeeper”
  • City Hall Security
nucleolus
NUCLEOLUS
  • Description
    • Irregular/ Spherical bodies within nucleus
  • Function
    • Storehouse of RNA
    • Synthesis of RNA to make Ribosomes
    • Disappears during cell reproduction
  • Mayor’s Office inside City Hall
chromatin threads
CHROMATIN THREADS
  • Description
    • Long, tin coiled fibers containing DNA and Protein
  • Function
    • Contains DNA code that controls all cell reactions
    • Carriers genetic code that determines heredity.
  • City Blueprints

cell membrane
CELL MEMBRANE
  • Structure
    • Flexible, thin porous two-layered structure surrounding cell
  • Function
    • Controls movement in and out of cell
    • Shapes and protects the cell
  • Security Fence around City
cytoplasm
CYTOPLASM
  • Structure
    • Semifluid/ jelly-fluid material of cell surrounding nucleus
  • Function
    • Main storehouse of chemicals and organelles
    • Where chemical reactions of life occur
  • City Grounds/ Lawns
endoplasmic reticulum e r
ENDOPLASMIC RETICULUM (E.R.)
  • Structure
    • Complex series of membrane channels that form branching, net-like maze from cell membrane to nuclear membrane
  • Function
    • Transport of materials throughout cell
    • Divides cell into compartments
  • Highway System
ribosomes
RIBOSOMES
  • Description
    • Tiny dense bodies which lie on the edges of E.R. or in clusters in cytoplasm (Free ribosomes)
  • Function
    • Site of Protein Synthesis
  • Factories
golgi complex
GOLGI COMPLEX
  • Structure
    • Stack of flattened saccules. “Stacks of stacks.”
  • Function
    • Synthesis, Storage, Secretion of Large Molecules
    • Package and deliver molecules outside of cell
    • May manufacture lysosomes
  • Post Office or Fed-Ex Center
