Vedclass · Answer

(A) Primary growth in plants refers to the increase in length of the plant body.This growth is primarily driven by the activity of apical meristems,which include the shoot apical meristem and the root apical meristem.These meristems continuously divide to produce new cells that differentiate into primary tissues,leading to the elongation of stems and roots.Vascular cambium is responsible for secondary growth (increase in girth),not primary growth.Root caps protect the root meristem but do not contribute to growth themselves.Primary growth continues throughout the life of the plant at the tips of roots and shoots.
