CELLS

  • The smallest organized form of living protoplasm

    • Protoplasm: Living matter within a cell

  • Can be one simple organism Amoeba

  • Millions of cells can make up an organ and have a specific job. This would create a complex organism

2 Main Types of CELLS

  • Eukaryotic: Cells with a NUCLEUS

    • Plant, Animal, Fungi, & Most Protists

  • Prokaryotic: Cells WITHOUT a Nucleus

    • Bacteria & Archaea


Cell membrane

FOUND IN:Plant CellsAnimal Cells

CELL MEMBRANE

Separates cell from its environment

Controls substances passing in and out of cell (analogy: like a window screen)


Cells 5048208

NUCLEUS

FOUND IN:Plant CellsAnimal Cells

  • “Command Central” of the cell

  • Contains chromosomes (analogy:

  • like a brain)


Cells 5048208

CHROMOSOMES

  • Structures that contain DNA

  • DNA is instructions for the cell’s activities (analogy: like a recipe)

NUCLEAR ENVELOPE

  • Membrane that surrounds the nucleus

  • Lets materials in and out (analogy:

  • like a skull)

CYTOPLASM

FOUND IN:Plant CellsAnimal Cells

  • Jelly-like substance that fills the cell

  • (analogy: like “packing peanuts”)


Cells 5048208

MITOCHONDRIA

FOUND IN:Plant CellsAnimal Cells

  • Breaks down food into energy to be used by the cell

  • (analogy: powerhouse of the cell)

RIBOSOMES

FOUND IN:Plant CellsAnimal Cells

  • Small structures that make proteins

  • that the cell needs

  • Ribosomes use the info from DNA to make the proteins (analogy: factory workers)

ENDOPLASMIC RETICULUM

  • Tube-like structure that contains ribosomes

  • ER transports proteins throughout the cell (analogy: roadways or tunnels)

FOUND IN:Plant CellsAnimal Cells


Cells 5048208

GOLGI BODIES

FOUND IN:Plant CellsAnimal Cells

  • Packages proteins made by the ribosomes to be sent out of the cell

  • (analogy: the mailroom workers in a factory)


Cells 5048208

LYSOSOMES

FOUND IN:Plant CellsAnimal Cells

  • Helps cell digest proteins and old cell parts - they basically clean up the cell

  • (analogy: custodians)


Cells 5048208

VACUOLES

FOUND IN:Plant Cells (ONE BIG VACUOLE)Animal Cells (MANY SMALL ONES)

  • Storage areas in cell for water, food and waste (analogy: water tank or refrigerator)


Cells 5048208

CELL WALL

FOUND IN:Plant Cells

  • Rigid outer layer made of cellulose

  • Supports and protects plant cells (analogy: wall surrounding a castle)


Cells 5048208

PLASTIDS

FOUND IN:Plant Cells

  • Contain pigments that give plants their color (analogy: human skin tones)


Cells 5048208

CHLOROPLASTS

  • Plant cell structures that contain the pigment CHLOROPHYLL (green pigment)

  • Chlorophyll traps energy from the sun for photosynthesis (analogy: solar panels)
