Axillary bud and terminal bud derived from the activity of : -

  1. Apical meristem
  2. Parenchyma
  3. Lateral meristem
  4. Intercalary meristem

Answer

(1) Apical meristem

Solution

The terminal bud at the tip of the shoot is the shoot apical meristem itself with its young leaf primordia.

As per NCERT, during the formation of leaves and elongation of stem, some cells 'left behind' from the shoot apical meristem constitute the axillary bud; such buds are present in the axils of leaves and can form a branch or a flower.

∴ Both axillary and terminal buds are derived from the activity of the apical meristem.
