Meristematic Tissue · Botany

Cells of meristematic tissue usually lack ergastic substances because:

  1. They are completely dead, empty cells
  2. They do not possess a nucleus at all
  3. They are waterproofed by a layer of suberin
  4. They divide rapidly and use energy at once
Show answer and explanation

Correct answer: They divide rapidly and use energy at once

Ergastic substances are non-protoplasmic materials like starch grains or crystals usually stored in mature cells. Meristematic cells are metabolically hyperactive and utilize nutrients immediately for growth rather than storing them.
