Answer 1

Question

Chapter 18, Problem 1SQ

Summary Introduction

Concept introduction: Eukaryotes belong to the domain Eukarya or Eukaryota. They have various membrane-bound organelles present in them. Eukaryotes have the ability to reproduce both sexually and asexually.

Expert Solution & Answer

Answer to Problem 1SQ

Correct answer: Compared to prokaryotes, eukaryotes have a nucleus. Therefore, option c. is correct.

Explanation of Solution

Reason for the correct statement:

Eukaryotes have a well-defined nucleus with a nuclear membrane. The nucleus of the eukaryotic cells contains DNA. But prokaryotes do not have a nucleus.

Option c. is given as “have a nucleus”. As eukaryotes have a nucleus compared to prokaryotes, option c. is correct.

Reasons for the incorrect statement:

Option a. is given as “do not have membrane-enclosed compartments in their cells”. Eukaryotes have membrane-enclosed compartments in their cells. So, option a. is incorrect.

Option b. is given as “exhibit a much greater diversity in modes of nutrition”. Prokaryotes exhibit greater diversity in modes of nutrition. So, option b. is incorrect.

Option d. is given as “are more widespread”. Prokaryotes are wide spread compared to eukaryotes. So, option d. is incorrect.

Hence, options a., b., and d. are incorrect.

Conclusion

Eukaryotes have a true nucleus that is not present in prokaryotes.
