Cells

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.

When observing a piece of onion skin under magnification, a student records the following entry in his Science Journal. Which observation would have been the same for any type of living organism that the student observed?

• Made of at least one cell
• Nucleus in the middle
• Walls present between
• Looks practically empty

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

An organelle that eukaryotes have, but prokaryotes do not have, is a -

• cell membrane.
• nucleus.
• cytoplasm.
• ribosome.

Two cells are represented by the following diagram. 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

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

• animal cells require energy from outside food sources.
• the cell membrane on an animal cell is much more rigid.
• the genetic material of animal cells is stored in a nucleus.
• animal cells grow at a much slower rate than bacteria cells.

What is one characteristic that all living things have in common? All living things -

• are made up of cells.
• eat food for energy.
• sleep for half of every day.
• reproduce by dividing entirely.

Several types of organisms are described in the following table. Which group is the group of prokaryotic organisms?

• Group 1
• Group 2
• Group 3
• Group 4

A chimpanzee and a pine tree have very little in common. However, because they are both living things, we can be certain that they both 

• use the sunlight to make their own food.
• are made up of one or more cells.
• travel with other members of their species.
• have a skeleton which allows them to move.

When comparing a prokaryotic cell to an eukaryotic cell, an important difference is that the prokaryotic cell –

• is simple, performing limited functions.
• is relatively small in size and unorganized.
• has its genetic information stored in the nucleus.
• has no structures that allow it to store food.
