Question:
Which one of the following statements is INCORRECT about the prokaryotic and eukaryotic organisms on the Earth?
Which one of the following statements is INCORRECT about the prokaryotic and eukaryotic organisms on the Earth?
Show Hint
Prokaryotes outnumber and outmass eukaryotes by far, with their total biomass being greater than that of eukaryotes.
Updated On: Dec 11, 2025
- Prokaryotes have more sequence diversity in their DNA than do eukaryotes
- Prokaryotes outnumber eukaryotes
- Prokaryotes survive in more extreme environments than do eukaryotes
- The cumulative biomass of prokaryotes is less than that of eukaryotes
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Analyzing the Statements.
- (A) Correct. Prokaryotes tend to have a higher sequence diversity in their DNA due to faster mutation rates.
- (B) Correct. Prokaryotes outnumber eukaryotes by orders of magnitude in terms of population.
- (C) Correct. Prokaryotes can survive in a wide range of extreme environments (e.g., high temperature, salinity, acidity).
- (D) Incorrect. The cumulative biomass of prokaryotes is actually greater than that of eukaryotes. Prokaryotes dominate in terms of number and biomass in many ecosystems.
Step 2: Conclusion.
Thus, the incorrect statement is (D).
- (A) Correct. Prokaryotes tend to have a higher sequence diversity in their DNA due to faster mutation rates.
- (B) Correct. Prokaryotes outnumber eukaryotes by orders of magnitude in terms of population.
- (C) Correct. Prokaryotes can survive in a wide range of extreme environments (e.g., high temperature, salinity, acidity).
- (D) Incorrect. The cumulative biomass of prokaryotes is actually greater than that of eukaryotes. Prokaryotes dominate in terms of number and biomass in many ecosystems.
Step 2: Conclusion.
Thus, the incorrect statement is (D).
