1. Prokaryote vs Eukaryote Cells

2. Cells have evolved two different types:
Prokaryotes
Eukaryotes

3. Prokaryote cells are smaller and simpler
Commonly known as bacteria
microns or micrometers in size
Single-celled(unicellular)
Filamentous (strings of single cells)

4. These are prokaryote

5. Prokaryote cells are simply built (example: E. coli)
capsule: slimy outer coating
cell wall: tougher middle layer
cell membrane: delicate inner skin

6. Prokaryote cells are simply built (example: E. coli)
cytoplasm: inner liquid filling
DNA in one big loop
pilli: for sticking to things
flagella: for swimming
ribosomes: for building proteins

7. Prokaryote lifestyle unicellular: all alone colony: forms a film
filamentous: forms a chain of cells

8. Prokaryote Feeding Photosynthetic: energy from sunlight
Disease-causing: feed on living things
Decomposers: feed on dead things

9. Eukaryotes are bigger and more complicated
Have organelles
Have chromosomes
can be multicellular
include animal and plant cells

10. Organelles are membrane-bound cell parts
Mini “organs” that have unique structures and functions
Located in cytoplasm

11. Prokaryotes vs. Eukaryotes
All living things are classified into two major groups. They are either Prokaryotes or Eukaryotes.
Prokaryotes
Eukaryotes
No definite nucleus
No membrane bound organelles
All are bacteria!
Unicellular
Have a defined nucleus
have membrane-bound organelles
(mitochondria, lysosomes, etc.)
May be single or multi-cellular
Now think of what Prokaryotes and Eukaryotes have in common and use them to complete the following bubble map. Remember the characteristics of all living things!!
