1.

Is it possible for an organism to survive with only one cell?

a)

no, because organisms need many cells to be able to perform functions for life

b)

yes, as long as the organisms can perform all functions needed for life in that one cell

c)

no, because organisms cannot complete all necessary functions for life in such a small space

d)

yes, as long as the organism has multiple specialized parts with each performing a specific function

2.

b)

It has many cells that function as a complex system.

c)

It has one cell that can carry out everything it needs to survive.

It has one cell that needs other cells to help it survive and thrive.

4.

Which best describes a difference between single-celled organisms and multicellular organisms?

a)

Single-celled organisms are simple, while multicellular organisms are complex.

b)

Single-celled organisms have many functions, while multicellular organisms have one function.

c)

Single-celled organisms can live without water, while multicellular organisms cannot live without water.

b)

Grasshoppers are single-celled organisms because they are made up of one cell that carries out all of their life processes.

c)

Grasshoppers are single-celled organisms because they are made up of many cells that carry out all of their life processes.

d)

Grasshoppers are multi-celled organisms because they are made up of many cells that carry out all of their life processes.
