2 Main Types of CELLS n Eukaryotic: Cells with a NUCLEUS n Plant, Animal, Fungi, & Most Protists n Prokaryotic: Cells WITHOUT a Nucleus n Bacteria & Archaea

CELL MEMBRANE FOUND IN: Plant Cells Animal Cells ØSeparates cell from its environment ØControls substances passing in and out of cell (analogy: like a window screen)

FOUND IN: Plant Cells Animal Cells NUCLEUS “Command Central” of the cell Ø Contains chromosomes (analogy: like a brain) Ø

CHROMOSOMES FOUND IN: Plant Cells Animal Cells Structures that contain DNA Ø DNA is instructions for the cell’s activities (analogy: like a recipe) Ø http: //www. le. ac. uk/ge/genie/vgec/sc/cellcycle. html

NUCLEAR ENVELOPE FOUND IN: Plant Cells Animal Cells Membrane that surrounds the nucleus Ø Lets materials in and out (analogy: like a skull) Ø http: //kconline. kaskaskia. edu/bcambron/Biology%20117/Cells. htm

CYTOPLASM FOUND IN: Plant Cells Animal Cells Ø Jelly-like substance that fills the cell (analogy: like “packing peanuts”)

MITOCHONDRIA FOUND IN: Plant Cells Animal Cells Ø Breaks down food into energy to be used by the cell (analogy: powerhouse of the cell) http: //www. cartage. org. lb/en/themes/sciences/zoology/Animal. Physiology/Anatomy/

FOUND IN: Plant Cells Animal Cells RIBOSOMES Small structures that make proteins that the cell needs Ø Ribosomes use the info from DNA to make the proteins (analogy: factory workers) Ø http: //hyperphysics. phy-astr. gsu. edu/Hbase/biology/imgbio/ribosome. gif

ENDOPLASMIC RETICULUM FOUND IN: Ø Tube-like structure that contains ribosomes Plant Cells Animal Cells Ø ER transports proteins throughout the cell (analogy: roadways or tunnels)

GOLGI BODIES FOUND IN: Plant Cells Animal Cells Packages proteins made by the ribosomes to be sent out of the cell (analogy: the mailroom workers in a factory) Ø

LYSOSOMES FOUND IN: Plant Cells Animal Cells Ø Helps cell digest proteins and old cel parts - they basically clean up the cel (analogy: custodians)

VACUOLES FOUND IN: Plant Cells (ONE BIG VACUOLE) Animal Cells (MANY SMALL ONES) Ø Storage areas in cell for water, food and waste (analogy: water tank or refrigerator)

CELL WALL FOUND IN: Plant Cells Rigid outer layer made of cellulose Ø Supports and protects plant cells (analogy: wall surrounding a castle) Ø

PLASTIDS FOUND IN: Plant Cells Ø Contain pigments that give plants their color (analogy: human skin tones)

CHLOROPLASTS FOUND IN: Ø Plant cell structures that contain the Plant Cells pigment CHLOROPHYLL (green pigment) Ø Chlorophyll traps energy from the sun for photosynthesis (analogy: solar panels) http: //allyncali 16. tripod. com/id 1. html
