Question 5

chromosomal DNA is generally found here in bacterial cells

Answer 5

in the nucleoid

Question 6

A newly discovered unicellular organism isolated from acidic mine drainage is found to contain a cell wall, a plasma membrane, two flagella, and peroxisomes. Based on this information only, the organism is most likely to be ________.

Answer 6

motile eukaryote

Question 7

Which parameter is most likely to limit the maximum size of a cell?

Answer 7

the ratio of surface area to volume of cytoplasm

Question 8

If you are provided with a cube of modeling clay, what can you do to decreases its surface area relative to its volume?

Answer 8

Round the cube into a sphere

Question 9

If model cells have shapes that approximate rectangular solids, which of the following dimensions will provide the cell with the greatest ratio of surface area to volume (all units are in micrometers, μm)?
A) 202020
B) 101010
C) 101020
D) 102020

Answer 9

B) 101010

Question 10

The volume and surface area for three different cells are listed in the table

Based on data from the table, which cell will be able to eliminate wastes most efficiently?

Answer 10

Cell 2 because it has the highest ratio of surface area to volume, which facilitates the exchange of materials between a cell and its environment.
