5.L.1.1 Cells

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

• by having specialized cells

• by being larger than most organisms

• by being smaller than most organisms

• by performing all processes in one 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.

• Multicellular organisms contain many specialized cells necessary for survival, while single-celled organisms can survive alone.

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.

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 best explains why an amoeba is considered a single-celled organism?

• It does not require all life functions to survive.

• It contains genetic instructions for reproduction.

• The entire organism is made up of several types of cells.

• The entire organism is one cell in contact with the external environment.

Which of these is a structure that is present in all organisms?

• a tissue

• a cell

• a stomach

• a brain

A unicellular organism is BEST described as being

• a complex organism

• a microorganism

• an organism with specialized cells

• an organism with different types of tissues

A single-celled 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?
