Explanation:
Detailed explanation-1: -Just as in roots, primary growth in stems is a result of rapidly dividing cells in the apical meristems at the shoot tip. Subsequent cell elongation then leads to primary growth.
Detailed explanation-2: -Apical meristem is present at the growing tips of stems and roots and increases the length of the stem and the root.
Detailed explanation-3: -Growth from the root and shoot tips resulting in increases in height and length is called primary growth. Growth that increases the thickness of stems and branches is called secondary growth.
