Cell OrganellesAnalogies & Color Coding
Welcome to the World of Cells!Welcome to the World of Cells!Cells make up all living things!
They come in many shapes and sizes!
They are the world of life science! http://www.youtube.com/watch?v=Ow0jH2E

What is a Cell? A cell is the smallest unit of life.
Your body is made up of trillions of cells with each one working hard to produce proteins. (Cell’s Main Job!)
These proteins are used as building blocks for many different things. For example, your hair and nails are made up of a special protein made by cells.
However, in order to carry out this important task, cells are made of tiny structures that work together. These tiny structures are called organelles. They work together just like a factory!
CELL MEMBRANECELL MEMBRANE
OrganellePlant,
Animal, or Both?
Structure and FunctionThis cell part is just like…
Cell Membrane
▪ Both Surrounds the outside of the cell.
▪Controls what substances can enter and exit the cell
▪Security Guard
CELL WALLCELL WALL
OrganellePlant,
Animal, or Both?
Structure and FunctionThis cell part is just like…
Cell Wall Plant ▪ Surrounds the cell membrane ;It is a tough and rigid covering made of cellulose
▪ Gives a plant shape, support, and protection
Cement between the bricks in a Brick Wall
CYTOPLASM (Cytosol)CYTOPLASM (Cytosol)
OrganellePlant,
Animal, or Both?
Structure and FunctionThis cell part is just like…
Cytoplasm (cytosol)
▪Both ▪ Jelly-like fluid in cell
▪Holds all other organelles in place
▪ Jell-O
Animal Plant
Cell Membrane (9) = Medium BlueCytoplasm (2) = Light Blue
Cell Membrane (7) = Medium BlueCytoplasm (2) = Light BlueCell Wall (5) = Gold
NUCLEUSNUCLEUS
OrganellePlant,
Animal, or Both?
Structure and FunctionThis cell
part is just like…
Nucleus Both ▪ Nucleus controls and directs all of the cell’s activities
▪ The nucleus also protects a cell’s genetic material called chromatin. Another word for chromatin is DNA. DNA contains all the instructions for what proteins it should make.
▪ Check out glowing mice and transparent frogs: Mice - http://www.youtube.com/watch?v=n0UzdYRnMtY
▪ Frogs - http://www.youtube.com/watch?v=YZ4JmG-D9DM
▪ The nucleus is protected by a nuclear membrane. This membrane protects the nucleus allowing certain materials to enter and exit through pores.
▪ Brain
NUCLEOLUSNUCLEOLUS
OrganellePlant,
Animal, or Both?
Structure and FunctionThis cell part is
just like…
Nucleolus ▪ Both ▪ Dark region inside the nucleus
▪ The site where ribosomes are made
▪ Center of tootsie roll pop
Animal Plant
Nuclear Membrane (6) = PinkChromatin (12) = BlackNucleolus (13) = Purple
Nucleus is the entire circular structure
Nuclear Membrane (8) = PinkChromatin (12) = BlackNucleolus (9) = Purple
Nucleus is the entire circular structure
RIBOSOMESRIBOSOMES
OrganellePlant,
Animal, or Both?
Structure and FunctionThis cell part is just like…
Ribosome ▪ Both ▪Small, grain-like bodies floating in the cytoplasm or attached to the Endoplasmic Reticulum
▪Responsible for making proteins
▪ Factory Worker
Endoplasmic ReticulumEndoplasmic Reticulum
OrganellePlant,
Animal, or Both?
Structure and FunctionThis cell part is
just like…
ER ▪ Both ▪ A maze of tube-like membranes.
▪ Rough ER▪ studded with ribosomes▪ Acts as a passageway for protein
material sending it to the Golgi body
▪ Smooth ER▪ does not have ribosomes▪ Acts as a passageway for non-protein
material (fats and carbohydrates)
Assembly Line
Subway Tunnel
Animal Plant
Rough ER (7) = YellowSmooth ER (11) = Medium OrangeRibsomes (8) = Leave as Black Dots
Rough ER (10) = YellowSmooth ER (11) = Medium OrangeRibsomes (13) = Leave as Black Dots
GOLGI BODYGOLGI BODY
OrganellePlant,
Animal, or Both?
Structure and FunctionThis cell
part is just like…
Golgi body
▪Both ▪Flattened stacks of membrane (looks like pita bread)
▪Works to package, tag, and ship a protein to its destination inside or outside of the cell.
▪ Mailroom
VESICLEVESICLE
OrganellePlant,
Animal, or Both?
Structure and FunctionThis cell part is
just like…
Vesicle Both ▪ Small membrane sacs
▪ Transports proteins from one part of the cell to another
▪ Factory Car
▪ Vesicle sounds like “Vehicle”
Animal Plant
Golgi Body (14) = BrownVesicles (3) = Dark Orange
Golgi Body (6) = BrownVesicles (15) = Dark Orange
VACUOLEVACUOLE
Organelle
Plant, Animal,
or Both?
Structure and FunctionThis cell part is just
like…
Vacuole ▪Both ▪Plants –Have 1 large vacuole filled with mostly water
▪Animals – Have many smaller vacuoles filled with food
▪Plant = Swimming Pool
▪Animal=Refrigerator
▪Vacuole sounds like “Vaccuum”
LYSOSOMELYSOSOME
OrganellePlant,
Animal, or Both?
Structure and FunctionThis cell part is just like…
Lysosomes ▪ Both ▪ Small membrane sacs
▪ Contains special chemicals to digest food, old cell parts, or waste
▪ Garbage Disposal
Animal Plant
Vacuole (4) = Dark BlueLysosome (10) = Light Red
Vacuole (4) = Dark Blue
MITOCHONDRIAMITOCHONDRIA
OrganellePlant,
Animal, or Both?
Structure and FunctionThis cell
part is just like…
Mitochondria ▪ Both ▪ A jelly-bean shaped structure with an outer membrane and inner membrane which is folded.
▪ Produces usable energy for the cell by breaking down sugar called glucose (powerhouse of the cell)
▪ Battery
CHLOROPLASTCHLOROPLAST
OrganellePlant,
Animal, or Both?
Structure and FunctionThis cell
part is just like…
Chloroplast ▪ Plant Only
▪ A green, jelly-bean shaped structure with an outer and inner membrane
▪ Captures sunlight and uses it to produce food (glucose) for a plant cell
▪ Solar panel
Animal Plant
Mitochondria (1) = Dark Red Mitochondria (1) = Dark RedChloroplasts (3) = Green
The Inner Life of a Cell is Spectacular! Now that you know a cell’s job is to
make proteins, watch these proteins in action as they work to make the inner life of a cell come alive.
Harvard University selected XVIVO to develop an animation that would take their biology students on a journey through the microscopic world of a cell http://www.youtube.com/watch?v=Mszlckmc4Hw
