Select the mismatch.

  1. Large central vacuoles – Animal cells
  2. Methanogens – Prokaryotes
  3. Gas vacuoles – Green bacteria
  4. Protists – Eukaryotes

Answer

(1) Large central vacuoles – Animal cells

Solution

As per NCERT, plant cells possess a large central vacuole, whereas animal cells have small vacuoles or lack them. ⇒ (1) is the mismatch.

∵ Methanogens are archaebacteria, i.e., prokaryotes.

∵ As per NCERT, gas vacuoles are found in blue-green, purple and green photosynthetic bacteria.

∵ Protists are unicellular eukaryotes.
