an organism with one cell that uses other cells to survive
an organism with many cells that work together to survive
an organism with many cells that battle each other to survive
an organism with one cell that performs all of its life processes
What is the main purpose of a single-celled organism?
to survive
to reproduce
to produce food for other organisms
to work with other single-celled organisms
Which is a characteristic of bacteria?
large in size
able to survive as a single cell
found only in one environmnet
made up of many different cells working together
How does an ant benefit from being a multicellular organism?
Ants have one specialized cell that performs a variety of tasks necessary for life.
Ants perform a variety of tasks to be able to survive so they need many specialized cells.
Ants hae one type of cell and this cell performs the same task to help them survive.
Ants are small organisms but depend of only two different types of cells to help them survive.
Which best describes the main job of most cells in multicellular organisms?
Cells work to keep themselves alive.
Cells work to keep the organism alive.
Cells work to release needed materials.
Cells work to store unneeded materials.
How are multicellular and unicellular organisms different?
Multicellular ogransims have more than one cell and are smaller than unicellular organisms.
Unicellular ogransims have more than one cell and are larger than multicellular organisms.
Unicellular ogransims have one cell and are smaller than multicellular organsisms.
Multicellular ogransims have one cell and are larger than unicellular organsisms.

The organism is unicellular.
The organism is microscopic.
The organism is multicellular.
The organism does not have any cells.
How is it possible for single-celled organisms to survive>
They are small and can easily avoid predators.
They have all of their needs met within one cell.
They have adapted to live only in specific environments.
They depend on other cells to obtain food, water, and other resources.
Which best describes a difference between single celled organisms and multicellular organisms?
Single celled organisms are simple, which multicellular organisms are complex.
Single celled organisms have many functions, which multicellular organisms have one function.
Single celled organisms can live without water, which multicellular organisms cannot live without water.
Single celled organisms can only be found in one environment, which multicellular organisms can be found anywhere on Earth.
Why does a human require specialized cells to live?
Specialized cells allow humans to adapt to changes in their environment.
Human bodies have systems that require cells with different functions.
Specialized cells allow for all life processes to occur in one cell.
Human bodies are simple and require few cells.
