Cell Test Review

How are multi-celled organisms different from single-celled organisms?

• Multi-celled organisms must reproduce.
•  Multi-celled organisms must obtain energy.
•  Multi-celled organisms have microscopic body structures.
•  Multi-celled organisms have specialized cells to perform life functions.

Which of the following states a difference between single-celledorganisms and multi-celled organisms?

• Single-celled organisms are dead while multi-celled organisms are alive.
• B. Single-celled organisms do not have organs while multi-celled organisms have organs.
• Multi-celled organisms are made up of cells performing the same function while single-celled organisms are not.

Sue and Allie read about different kinds of organisms. They read about an organism with a respiratory system, digestive system, skeletal system, and muscular system. Which can Sue and Allie most likely conclude about this organism?

• The organism is unicellular.
• This organism is microscopic.
• The organism is multi cellular.
• The organism does not have any cells.

Which best describes a function of survival that single-celled organismscannot perform?

• reproduction of cells
• obtaining nutrients for energy
• specialization and division of labor

Which best describes a single-celled organism?

• 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

A single-cell organism can do everything a cell from a multicellular organism can do except...

• specialize
• reproduce
• use energy
• make protein

Which of the following must get nutrients from a transport system?

• amoeba
• euglena
• skin cell
• bacteria

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

• Single-celled organisms are simple, while multicellular organisms are complex.
• Single-celled organisms have many functions, while multicellularorganisms have one function.
• Single-celled organisms can live without water, while multicellularorganisms cannot live without water.
• Single-celled organisms can only be found in one specificenvironment, while multicellular organisms can be found anywhere onEarth.

Why do multicellular organisms need transport systems?

• Most have cells that are not able to exchange gases with the outside environment.
• Most have cells that are unable to grow and survive in their environment.
• Most have cells that need food from sources outside their environment.
• Most have cells that require more energy to survive than single-celled organisms.

Which characteristic do single-celled organisms and multicellularorganisms have in common?

• Both have cells with specialized functions for each life process.
• Both perform all life processes within one cell.
• Both have a way to get rid of waste materials.
• Both are able to make food from sunlight.
