Chapter 1: Q4. (page 21)

The bacterium Thiomargarita namibiensis鈥攁t about 0.1 to 0.3 mm in diameter鈥攊s visible to the human eye. How does its size compare to the size of typical prokaryotic cells? How does it compare to the size of typical eukaryotic cells?

Short Answer

Expert verified

Thiomargarita namibiensis is 10-300 times larger than the prokaryotic cells and 30 times larger than the eukaryotic cells.

Step by step solution

01

Introduction

All living creatures contain one or more cells.Prokaryotes and eukaryotes are the two types of organisms.Prokaryotes, such as bacteria and archaea, are usually unicellular. In contrast, eukaryotes, such as protists, fungi, plants, and mammals, are mostly multicellular.

02

Comparing the size of typical cells

Thiomargarita namibiensis is a bacterium with a diameter of 0.1-0.3 mm. It's visible to the naked eye. Prokaryotic cells are smaller than eukaryotic cells, with diameters ranging from1 to 10 渭m in diameter. The diameter of a normal eukaryotic cell ranges from 10 to 100饾泹m. The bacterium Thiomargarita namibiensis has a diameter of 100-300渭m.

03

Conclusion

Hence,Thiomargarita namibiensis is 10-300 times the size of prokaryotic cells and 30 times the size of eukaryotic cells.
