Multiple Choice

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

• no, because organisms need many cells to perform all functions for life

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

Multiple Choice

Which best describes how single-celled and multicellular organisms are similar?

• both require organs to help with life function

• neither require transport systems to survive

• both require energy to survive

• both rely on many other cells to survive

Multiple Choice

Phytoplankton is a single-celled organism. Which describes phytoplankton?

• It is a complex organism that has many cells

• it carries out all life functions in only one cell

• It has one cell that needs other cells to survive

Multiple Choice

Bacteria often live inside the body of a living host, such as a goat. Which best describes how bacteria carry out the processes necessary for survival?

• Bacteria borrow cells from the host to carry out life processes.

• Bacteria use their many different cells to carry out life processes.

• Bacteria are made up of one cell which is responsible for carrying out all life processes.

• Bacteria use their many different cells as well as cells from the host to carry out life processes.

Multiple Choice

Why do humans require many different types of cells to survive?

• Human cells are specialized and work independently to perform different functions.

• Human cells are specialized and work together to perform the same function.

Multiple Choice

Which is the best way to classify lizards?

• Lizards are multi-celled organisms because they are made up of one cell that carries out all of their life processes.

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

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