What is an Organism?
Definition:
Organism – anything that can live on its own

8. Unicellular Organisms

9. Unicellular Organisms
Definition:
Unicellular organism – an organism made of only one cell
Information:
These organisms are very small and need to be seen with a microscope.
Perform the same tasks as multicellular organisms
They move, eat, reproduce and expel waste.

10. Unicellular: Common Names
Microscopic Organisms
Microorganisms
Really small living things

11. Examples of Unicellular Organisms
Amoeba
Paramecia
E. Coli
Bacteria
Unicellular Fungi
Unicellular Yeasts

12. Images of Unicellular Organisms

13. THE AMOEBA

14. Have characteristics of an animal cell
The Amoeba
Have characteristics of an animal cell
Live in fresh and salt water environments and decaying vegetation sites.
Are predators – they prey on algae and bacteria
Uses osmosis to get water and diffusion to get oxygen and dispose of carbon dioxide.

16. Bacteria
A unicellular microorganism lacking organelles and an organized nucleus
Some can cause disease.

23. Why do you believe in your point of view?
Write it out!
The sorted 4-corners groups will write down informational statements about:
Why do you believe in your point of view?
Why it is different from the other points of view groups in the room?

24. Multicellular Organisms

25. Multicellular Organisms
Definition:
Multicellular organism – an organism made of two or more cells
Information:
These organisms are able to be seen with the naked eye.
These organisms need all parts of itself to survive.

26. Multicellular Organisms
Rely on a variety of cells to perform cellular functions. These are called “specialized cells”.
Specialized cells perform duties such as digestion or movement.
Example: Eyes, Muscles and Tongue. (what duties do these perform?)
Just like organelles, each cell has a job to play

27. Examples of Multicellular Organisms
Humans
Cats
Dogs
Insects
Birds
Flowers
Mold
Trees

31. 1. Write 2 Test Questions (2 minutes)
Example:
Explain the difference between unicellular and multicellular organisms.
How can bacteria be useful?
Trade with a classmate
See if you can answer the questions. (3 minutes)

32. Multicellular Question: What type of organism is a hamster? Answer:
Sample Question
Question: What type of organism is a hamster?
Answer:

34. 2. Question to Consider
Why do you think small cells are more efficient (better at what they do) than large cells?
2 minutes

35. 3. Questions to Consider: 5 minutes
Consider the following:
A unicellular organism is a living thing that meets all of the basic needs with just one cell. A multicellular organism can require up to several trillion cells to do the same thing.
a. Which type do you consider to be more advanced? Explain your reasoning.
b. Are multicellular organisms better or smarter? Why do you think so?

36. The Sponge Dilemma– Your Choice
Write three questions you would like to ask a scientist who is working on a new way to use sponges.
Write three reasons scientists should continue researching ways to use what we learn about sponges.
Come up with at least 1 reason why it is good sponges can re-grow in clumps but are still unicellular.
Where do you think sponges fit in the evolutionary history of multicellularity? Before or after it/ Why?

38. What Interested Me? Why Should I Care? Don’t Forget!
