Unicellular vs. Multicellular Organism

How can a Paramecium carry out all of life’s functions?

• by having specialized cells

• by being larger that most organisms

• by being smaller that most organisms

• by performing all processes in one cell

Which is the order of cellular organization from least to most complex in

multicellular organisms?

• cell, tissue, organ, organ system, organism

• tissue, cell, organ, organ system, organism

• cell, organ, tissue, organ system, organism

• organism, organ, organ system, tissue, cell

What is the difference between single-celled organisms’ and multicellular

organisms’ ability to survive?

• Multicellular organisms depend on other organisms for survival, while

  single-celled organisms do not.

• Single-celled organisms depend on other organisms for survival, while

  multicellular organisms do not.

• Single-celled organisms contain many specialized cells necessary for

  survival, while multicellular organisms do not.

• Multicellular organisms contain many specialized cells necessary for survival,

  while single-celled organisms can survive alone.

Which best explains why a human needs many cells to survive?

• Each individual cell is too small to function alone.

• Each cell joins with other cells to form one massive cell.

• Each cell works with other cells to perform all necessary life functions.

• Each cell absorbs a different gas from the environment necessary for

  human survival.

Which accurately explains how an organism is capable of survival?

• An amoeba can perform all of life’s processes even though it is single-celled.

• A grasshopper can live off only one food source even though it is single-celled.

• A fish can exist if it lives in a group with many organisms even though it is single-celled.

• An earthworm can survive by using its long, straight digestive system even though it is single-celled.
