Question

Select the mismatch.

• A. Gas vacuoles - Green bacteria
• B. Large central vacuoles - Animal cells
• C. Protists - Eukaryotes
• D. Methanogens -Prokaryotes

Answer 1

The Correct Option is B

The correct answer is:

Option 2: Large central vacuoles - Animal cells

Explanation:

Option 1: Gas vacuoles - Green bacteria: This is correct. Gas vacuoles are found in certain types of bacteria, particularly in cyanobacteria and green bacteria, and they help regulate buoyancy in water.

Option 2: Large central vacuoles - Animal cells: This is incorrect. Large central vacuoles are typically a characteristic of plant cells, not animal cells. In plant cells, the central vacuole plays a significant role in maintaining turgor pressure, storing nutrients, and waste products. Animal cells may have smaller vacuoles, but they do not have the large central vacuole that is typical in plants.

Option 3: Protists - Eukaryotes: This is correct. Protists are indeed eukaryotic organisms, which means they have a defined nucleus and other membrane-bound organelles.

Option 4: Methanogens - Prokaryotes: This is correct. Methanogens are a type of prokaryotic organism that produce methane as a metabolic byproduct. They belong to the domain Archaea.

Summary:

The mismatch is Option 2 because large central vacuoles are found in plant cells, not animal cells.
