Which of the following correctly describes how a scientific tool could be used by a scientist to determine if a cell is prokaryotic or eukaryotic? The scientist could use -

• a thermometer to measure the heat inside the cell.

• a graduated cylinder to find the volume of the cell.

• a triple-beam balance to find the mass of the cell.

• a microscope to determine if the cell has a nucleus.

Which of the following would be distributed throughout a prokaryotic cell, but be found restricted to the nucleus of an eukaryotic cell?

• Ribosomes

• DNA

• Cell membrane

• Chloroplasts

Which of the following statements is an accurate conclusion that can be drawn about these two cells?

• Cell 1 is a prokaryotic cell due to the presence of ribosomes.

• Cell 2 is a prokaryotic cell due to the presence of cytoplasm.

• Cell 1 is an eukaryotic cell due to the presence of a flagellum.

• Cell 2 is an eukaryotic cell due to the presence of a nucleus.

All living things share some characteristics. For example, all organisms -

• are made up of one or more cells.

• make their own food from sunlight.

• have a skeleton to provide support.

• emerge, at birth, from some type of egg.

In order to classify a cell as prokaryotic or eukaryotic, it must be determined if the cell –

• grows larger throughout its life.

• can move from place to place.

• is able to make copies of itself.

• has its genetic material in a nucleus.

Animal cells are considered eukaryotic and bacteria cells prokaryotic. This is because -

• animal cells grow at a much slower rate than bacteria cells.

• the cell membrane on an animal cell is much more rigid.

• animal cells require energy from outside food sources.

• the genetic material of animal cells is stored in a nucleus.

Which group is the group of prokaryotic organisms?

• Group 1

• Group 2

• Group 3

• Group 4
