Detailed explanation-1: -If it is cut then the growth will gradually stop within the plant.
Detailed explanation-2: -However, if the shoot apical meristem is removed, by pruning for example, then the axillary meristems will grow into new flowering shoots and branches [fig. 9.9]. This phenomenon by which the growth of apical meristems is suppressed by the shoot apical meristem is called apical dominance.
Detailed explanation-3: -If the apical meristem of a branch is damaged or cut, the nearest node will begin to develop and form a bud and grow out. If the apical meristem in the roots and leaves are cut or damaged, then growth there will stop.
Detailed explanation-4: -Growth in length occurs in the region of elongation. Thus, if the apical meristem is damaged, the length of the young plant will get affected. The primary tissue of the root matures in the elongation zone, completing the process of cell differentiation.
Detailed explanation-5: -No, they cannot continue growing. This is because the apical meristematic tissues essential for their growth is present on tips. If the tips are removed, the roots can’t grow.
