1. Warm UP Warm up: Grab notebook and pencil box Agenda:
Bill Nye: The Cell
Notes on Cell Theory
Microscope Intro

2. Bill Nye on Cells

3. The Cell Theory and Types of Cells
Bacterial Cell
The Cell Theory and Types of Cells
Animal Cell
Plant Cell

4. The Cell Theory Song 

5. The Cell Theory The cell theory has 3 major tenets:
All living things are made of one or more cells.
Cells are the basic unit life.
New cells are made by other cells.
The ability of cells to divide to form new cells is the basis for all reproduction (both sexual and asexual) and for the growth and repair of all multicellular organisms.
The Cell Theory

6. Unicellular vs. Multicellular
It is the LOWEST LEVEL of structure capable of life and are microscopic.
Don’t forget:
Unicellular organisms are made up of one cell only
Multicellular organisms are made up of many cells, like us!
Unicellular vs. Multicellular

7. Prokayotic vs. Eukaryotic Cells… a song too 

8. Both main types of cells contain cell membrane, DNA, cytoplasm, and ribosomes.
Prokaryotic Cells
Do not have a true nucleus
DNA is a chemical compound that stores and transmits genetic information
So, the cell’s DNA is not completely separated from the rest of the cell by a nuclear membrane (envelope)
2. Eukaryotic Cells
Have a nucleus where DNA is found
2 Main Types of Cells

9. A Little More about Prokaryotic Cells…
Do not have most organelles
Organelles = tiny “organ-like” structures in the cell
Most prokaryotes are unicellular organisms, such as bacteria.
Much smaller than eukaryotic cells
A Little More about Prokaryotic Cells…

10. 2 Types of Eukaryotic Cells
Eukaryotic cells are much more complex and larger than their simple cousins the prokaryotic cell.
They contain MANY membrane-bound organelles
Most are Multicellular, few unicellular
We will talk more about the inner workings of the eukaryotic cell tomorrow, but for now we are going to learn the basics of the 2 types of eukaryotic cells:
Plant Cells
Animal Cells
2 Types of Eukaryotic Cells

11. Plant vs. Animal Cells Rap 

12. Plant vs. Animal Cells Plant Cells:
Have a cell wall, which helps with cell support
Have a central vacuole, which acts as a water storage center for the plant cell
Contain chloroplast, where photosynthesis takes place
Photosynthesis = process through which plants get their energy by converting sunlight and energy into glucose
Plant vs. Animal Cells

13. Plant vs. Animal Cells Animal Cells: Do not have a cell wall
Do not have a central vacuole, but may have a few tiny vacuoles/vesicles
Do not contain chloroplasts

14. NOW…..
