What does unicellular mean?
What is an organism?
A dead animal
A living thing
Which of the following is a single-celled organism?
Select a unicellular organism?
Which one is NOT a life process?
Get rid of waste
Shake it off
Grow and develop
Select the unicellular organisms that produce their own food. (They are also classified as producers/plants)
Euglena and algae
Bacteria and snail
Tree and paramecium
Flower and algae
What makes unicellular organisms unique and simple?
They can do all life process as one cell.
They can fly and eat at Zaxby’s.
They can survive working with other single-celled organisms.
Why do multicellular organisms need so many cells?
They need specialized cells to survive. Specialized cells perform a specific job/function.
They need many cells to all do the same job/function.
They need many cells to have a dancing cell party.
What is the difference between multi-celled and single-celled’s organisms?
Single-celled organisms are “simple” and multi-celled organisms are “crazy.”
Single-celled organisms are “super” and multi-celled organisms are “complex.”
Single-celled organisms are “simple” and multi-celled organisms are “complex.”
True or False:
Single-celled organisms are able to live as one cell, and multi-celled organisms need many cells to live because each cell has specialized job.
Which best explains why both cats and humans are multicellular organisms?
They get energy from many food sources.
They get energy from a single food source.
They need many different types of cells working together to meet their basic needs.
How do bacteria control their life processes/basic functions?
Bacteria control their life processes within multi-cells.
Bacteria control their life processes within a single-cell.
Bacteria work with other cells to control all their life processes.
Why does a human require specialized cells to live?
Specialized cells allow humans to adapt to changes in their environment.
Human bodies have several body systems which require cells with different functions/jobs.
Specialized cells allow for all life processes to occur in one cell.
Which best explains how a single-celled organism can survive without other cells?
They do not need any substance from outside of the cell.
They are able to perform all necessary functions within one cell
They do not need to perform more than one function to survive.
Which best explains why amoeba are able to survive without specialized cells?
Amoeba are able to survive with the help of specialized cells.
Amoeba are able to survive with the help of other organisms.
Amoeba are able to survive because they carry out all life functions.
Why do humans require many different types of cells to survive?
Human cells are identical and work together to perform the same function.
Human cells are specialized and work independently to perform different functions.
Which best describes a difference between single-celled organisms and multi-cellular organisms?
Single-celled organisms are simple, while multi-cellular organisms are complex.
Single-celled organisms are complex, while multi-cellular organisms are simple.
Which statement would most likely be found in an article about multicelled organisms like plants?
Plants have a simple structure.
Plants contain only one cell that performs all functions.
Plants do not need to eat, remove waste, or reproduce.
Plants contain many specialized cells that perform different functions.
In what way are both humans and bacteria the same?
Both are living things.
Both are non-living things.
Both are multi-cellular organisms.
Both are single-celled organisms.
Which best describes a function of survival that single-celled organisms cannot perform?
obtaining nutrients for energy
grow and develop
get rid of waste
specialized cells that perform specific jobs
