Cell Theory
(Schleiden and Schwann)
1.
All living things are made up of one or
more cells
2.
Cells are the basic units of structure and
function in organisms
3.
All cells come from pre-existing cells
2 main types of cells
 Prokaryotes
 Eukaryotes
(p. 57)
(p58-59)
Prokaryotes



No Nucleus
No Organelle
Single Celled
Organisms
(bacteria)
Eukaryotes
Eu – True
Karyo – Nucleus
 Nucleus
 Membrane Bound
Structures (organelle)
 Multicellular Organisms
Types of Eukaryotic Cells
 Plant Cells
Cell Walls
Chloroplasts
Central Vacuole
 Animal
Cells
More Mitochondria
Centrioles (used for cell division)
Eukaryotic Cells
Plant
Animal
Eukaryotic Organelle
 Nucleus
Function – Control
Center
Structure – membrane
bound structure that
houses DNA
Nucleolus is where
Ribosomes are
made
Ribosomes and the ER
 Endoplasmic
Reticulum –
like a system of conveyor belts
that move materials around
throughout the cell
 Ribosomes –
make proteins
can be free or attached to the ER
Vacuoles


Storage
Larger and more numerous in plant cells
Mitochondria




Power House
Supplies the cell energy
needs
Have their own DNA and
Ribosomes
Why do animal cells have
more mitochondria than
plant cells?
Power House
Chloroplasts
Found in Plant Cells
 Chloro – green
 Make Sugars

Golgi Apparatus

Packing and Shipping
Cell Membrane




Boundary
Functions to maintain homeostasis
All Cells have a cell membrane
More on the cell membrane later…
Lysosomes



Garbage Disposals
Get rid of unwanted
things in the cell
Pac – Man
Cell Wall


Plants and
Prokaryotes
Give cells their
strength and shape
Cytoplasm



Found in all cells
Gel-like liquid that fills the empty
space in the cell
Holds organelles in place
The end…
Except for one more cartoon…
