The Diversity of CellsHO#____C

Bellringer:

A ______________ is a cell that has an organized nucleus.


Cells and the cell theory

Cells and the Cell Theory

  • Robert Hooke

    • 1665

    • Cork

      • Saw “little boxes” AKA ___________

    • Plants and fungi

      • Cell _________

    • Living cells

      • “________”


Finding cells in other organisms

Finding Cells in Other Organisms

  • Anton van Leeuwenhoek

    • 1673

    • Pond scum

      • _________________

        • “little animals”

    • Animal blood

      • Differnece in ______ make-up

    • Bacteria

    • ______________

      • Discovered it makes bread rise…Yummo!


The cell theory

The Cell Theory

  • Schwann- 1839

    • All organsisms are made of ______ or more cells

    • The cell is the __________ unit of all living things

  • Virchow- 1858

    • All cells come from _________________ cells.

Cell size

Cell Size

  • Supersize Please

    • ________________ is one large cell

  • Value size

    • Most cells are _________________

      • Why???

      • Must have surface area to volume __________

        • ____________ cell = more food/wastes

        • Surface area grows ________________ than volume

          • Not enough ____________ in and not enough wastes out!!

          • We get a big useless blob!!!


Parts of a cell

Parts of a Cell

  • Cell ____________ (AKA: North Pole Walls and Guard Elves)

    • Protective layer that covers the cell’s surface and acts as a barrier

  • __________________ (AKA: A bowl full of jelly)

    • Fluid inside the cell

  • Organelles (AKA: the elves)

    • Perform __________________ inside the cell

  • Genetic Material (AKA: _______________)

    • All cells have ____________ at some point

    • Controls activities of a cell

    • Kept in a ______________ (AKA: Santa’s Office)

      • only in Eukaryotes

      • Humans- nucleus

      • ________________- no nucleus


Two kinds of cells

Two Kinds of Cells

  • _____________________- single celled organisms that do not have a nucleus or membrane bound organelles

  • Two Types

    • _____________

    • _____________


Bacteria

Bacteria

Single celled

Smallest cells known

Live anywhere


Archae

Archae

  • Single Celled

  • No Nucleus

  • Has:

    • Ribosomes

    • DNA

    • Cell membrane

  • Three types

    • ___________ loving

      • extremophile

    • ___________ loving

      • extremophile

    • ___________-making
