2. Learning Objectives:
 Differentiate prokaryotic and eukaryotic cells
according to their distinguishing features
 Site some examples of eukaryotic and
prokaryotic cells

3. Overview:
 Classifications of cell
 Prokaryotic cell
 Eukaryotic cell
 Examples of specialized eukaryotic cell

5. Prokaryotic Cell
 Smaller and simpler
 Single-celled
 Lacks a nucleus
 Presence of nucleoid

7. Prokaryote Life Style
Colony Filamentous

8. Prokaryotic Cell
DecomposersPhotosynthetic Disease-causing
Major Types of Prokaryotic Cell

9. Eukaryotic Cell
 Larger and more
complex
 Have membrane-
bound organelles
 Have chromosomes
 Include animal and
plants

10. Advantages
Prokaryotes Eukaryotes
Simple and easy to
grow
Can be specialized
Fast reproduction Multicellular
All the same Can build large bodies

11. Examples of Specialized Euk. Cells
 specialized to detoxify
blood and store glucose
as glycogen
Liver Cell

12. Examples of Specialized Euk. Cells
 specialized to deliver DNA
to egg cell
Sperm Cell

13. Examples of Specialized Euk. Cells
 specialized to capture as
much light as possible
Mesophyll Cell

14. How do Animal Cells Move?
 Some can crawl with pseudopods
 Some can swim with flagellum
 Some can move with cilia
Pseudopod Flagellum Cilia
