1. How many Cells does an Egg have?
4. Who was the first person to describe cells?
5. What are the parts to the cell theory?
ONE
Robert Hooke
All organisms are made of one or more cells.
The cell is the basic unit of all living things.
All cells come from existing cells.

2. All Cells Must Have…….
Cell membranes
Cytoplasm
DNA

3. Prokaryotic Cells Prokaryotes Do not have membrane bound organelles
Do not have a Nucleus
Classified into two major groups
Bacteria
Archaea

4. Bacteria Most Common Prokaryotes Smallest of all cells
Can live almost everywhere
DNA is long and circular
Shaped like a twisted rubber band
Not all Bacteria are bad!!
We have bacteria on our teeth, skin, and in our digestive systems! (They help us!!!)

5. Shapes of Bacteria Bacteria Have Three Shapes Sphere Rod Spiral Rods
Spherical
Spiral

6. Archaea
Different from bacteria because they have eukaryotic type ribosomes
Different cell wall and cell membrane from all other cells
Live in extreme environments
Extremophiles
Heat-Loving
Salt-Loving
Methane-making
Can live near volcanic vents

7. Eukaryotic Cells Have membrane bound organelles and a nucleus
Largest of all cells
10 times larger than bacteria cells
ALL other living things (that are not bacteria or archaea) are made of eukaryotic cells!
Can be unicellular (made of 1 cell) or multicellular (made of many cells

8. Prokaryotic Vs. Eukaryotic Cell

9. Super Slueth Find someone who can name the 3 things all cells have.
Find someone who can tell you the 2 major groups of prokaryotic cells.
Find someone who knows the most common type of prokaryote.
Find someone who knows the smallest type of cell.
Find someone who knows the 3 shapes of bacteria.
Find someone who knows how Archea differ from other bacteria.
Find someone who knows what eukaryotic cells have that prokaryotes do not.
Find someone who knows the largest type of cells.
Find someone who when called on can summarize this lesson. (Only need their name here.)
