1. Warm Up: On a brand new page Use your timeline notesC E B D A
All living things are made of one or more cells
Cells are the basic units of structure and function in all living things
All cells come from other cells

2. Critical question
Explain why prokaryotic cells are smaller than eukaryotic cells.

3. Engage: Describe what you see in this picture Color? Shapes?
Different sizes?
Engage:

4. Scientists to Remember
Robert Hooke (1665) – Observed “cells” in cork

5. Anton van Leeuwenhoek (1674)
Father of Microscopy
Saw tiny living things in pond water.
“Diatoms” – small aquatic protists

6. The Discovery of Cells Prokaryotic Before “no” nucleus Eukaryotic true

7. Compare prokaryotes & Eukaryotic cells
Has nucleus & nuclear envelope
Highly Organized
Protists
Proteins
Unicellular
Carbs
Has membrane bound Organelles
NO membrane bound organelles
Lipids
Nucleic acids
Ribosomes
DNA
animals
Multicellular
NO nucleus
Larger
Achaea
plants
Bacteria
fungi
smaller

8. Why do we learn about Macromolecules?
Carbohydrate
Protein
Nucleic Acid (DNA!)
Lipids (Fats)
Because these are what you are made of!!!
Mention Osmosis and Active Transport!
Protein

9. Eukaryotes Has a nucleus with a nuclear envelope
Bigger and more complex than prokaryotes
Have membrane bound Organelles
DNA – double-stranded and forms chromosomes (highly organized)
Can be uni- OR multicellular organisms
Ex: animals, plants, fungi, (some) protists

10. Prokaryotes NO nucleus
NO membrane bound organelles (does contain ribosomes)
ALL are unicellular
Smaller than eukaryotic cells
Believed to have given rise to eukaryotic cells
smaller and more simple
DNA – single strand and circular
Ex: ALL Bacteria and archea 10

11. Similarities Contain all four biomolecules Have ribosomes Have DNA
(lipids, carbs, proteins, and nucleic acids)
Have ribosomes
Have DNA
Similar Metabolism
Can be unicellular
Have cell/plasma membranes or cell wall

12. Pro Eu 1. Nuclues & Nuclear envelope
4. No Nuclues & No Nuclear envelope
3. DNA (EU – double stranded and Pro are single stranded
5. & 6. Archaea & Bacteria
2. Membrane bound organelles
9. No Membrane bound organelles
7. Highly Organized
8. Unicellular
14. smaller
10. animals
15. Protists
11. Larger
12. plants
16. Proteins
17. Carbohydrates
18. Lipids
19. Nucleic Acids
13. fungi
21. Multicellular
