Chapter 3: Problem 2

A typical prokaryotic cell _______ compared to a eukaryotic cell. a. is smaller in size by a factor of 100 b. is similar in size c. is smaller in size by a factor of one million d. is larger in size by a factor of 10

Short Answer

Expert verified
Answer: A typical prokaryotic cell is smaller in size by a factor of 100 compared to a eukaryotic cell.

Step by step solution

01

Understanding the terms

Prokaryotic cells are simpler and smaller than eukaryotic cells. They do not have a nucleus or membrane-bound organelles. Examples of prokaryotic cells are bacteria and archaea. Eukaryotic cells, on the other hand, have a nucleus and membrane-bound organelles. Examples of eukaryotic cells are plant cells, animal cells, and fungal cells.
02

Comparing the sizes

Let's compare the sizes of prokaryotic and eukaryotic cells: a. Prokaryotic cells are usually between 0.5 to 5 micrometers in size. b. Eukaryotic cells are generally larger, usually between 10 to 100 micrometers in size. From the above information, we can see that eukaryotic cells are generally larger than prokaryotic cells.
03

Evaluate the given statements

Let's evaluate each statement: a. Is smaller in size by a factor of 100. b. Is similar in size. c. Is smaller in size by a factor of one million. d. Is larger in size by a factor of 10.
04

Choose the accurate statement

Based on our analysis of prokaryotic and eukaryotic cell sizes, we know prokaryotic cells are smaller than eukaryotic cells. Comparing the sizes mentioned earlier, we can conclude that a prokaryotic cell is smaller in size, approximately by a factor of 10 to 20. The given options do not provide an exact factor, but option (a) is the closest to the correct answer. So, the correct answer is: A typical prokaryotic cell is smaller in size by a factor of 100 compared to a eukaryotic cell. Answer: a. is smaller in size by a factor of 100.
