Per NCERT, why was the 2-kingdom system found inadequate — leading to addition of PROTISTA as the third kingdom?
ANo reason was given
BPlants outnumbered animals
CAnimals don't move actually
DUnicellular organisms like Amoeba + Paramecium showed mixed traits (moving like animals but unicellular) that didn't fit Plantae or Animalia
Answer & Solution
Correct answer: D. Unicellular organisms like Amoeba + Paramecium showed mixed traits (moving like animals but unicellular) that didn't fit Plantae or Animalia
Per NCERT §12.5, the 2-kingdom system couldn't place unicellular organisms — leading to Protista (unicellular with true nucleus).
