Per NCERT, why are vacuoles GENERALLY ABSENT in meristematic cells?
ABecause vacuoles burst easily
BBecause the cells are small and rapidly dividing — large vacuoles would interfere with the dense cytoplasm and active division
CBecause plants don't need water
DBecause vacuoles are only in animal cells
Answer & Solution
Correct answer: B. Because the cells are small and rapidly dividing — large vacuoles would interfere with the dense cytoplasm and active division
Per NCERT §3.2.3, meristematic cells lack vacuoles to accommodate dense cytoplasm + many organelles needed for rapid division. The other options misstate.
