1. Unicellular Organisms

2. Unicellular Organisms
Definition:
Unicellular organism – an organism made of only one cell
Examples:
Bacteria
Unicellular yeast
Amoeba

3. Small and Simple
Unicellular organisms have a simple body construction because they are made up of only ONE cell
Since these organisms contain only one cell, you have to use a microscope to see them
Unicellular organisms are therefore known as microscopic organisms

4. A “one cell” team
Unicellular organisms are living things and therefore must carry out the essential functions of a living cell.
Such as transportation, respiration and synthesis of molecules
Since these organisms only contain one cell, all of these essential life functions are carried out by this ONE cell!!
More specifically, these life functions are being carried out by the organelles of this one cell.

5. Just Imagine
Just imagine if your teacher Ms. Blalock was not only your teacher but…
The principal of FHSA
The assistant principal
The math teacher
The history teacher
The school safety officer
I would have to play all of these roles to keep FHSA in control and functioning as a good high school

6. In a sense, unicellular organisms are doing the same thing.
The organelles of the one cell have to do all the necessary jobs to keep the bacteria alive

7. Multicellular Organisms

8. Multicellular Organisms
Definition:
Multicellular organism – an organism made of two or more cells
Examples:
Humans
Animals
Plants

9. Complex
Multicellular organisms have a complex body structure (organization) because they are made up of lots of cells
Since these organisms are made up of many cells, they can be seen with the naked eye
This means that you do not have to use a microscope to see them

10. Many players in the game
Since multicellular organisms are made up of many different cells, each of these different cells has a specific function(s)
This means that all of the cells of the organism are doing different functions and working together to keep the organism alive

11. All of these different cells work together to keep us alive

12. How is our school ran?
Here at FHSA, we have different people performing different jobs.
We have different people for each of the necessary jobs of the school (principal, assistant principal, science teacher, etc.)
Each person has a different job with a common goal of keeping the school functioning at its best
