Explanation:
Detailed explanation-1: -The correct answer is Option 1. Apical meristem is present at the growing tips of stems and roots and increases the length of the stem and the root. The girth of the stem or root increases due to lateral meristem (cambium).
Detailed explanation-2: -Undifferentiated cells in the meristems of plants allow indeterminate growth. Mitosis and cell division in the shoot apex provide cells needed for extension of the stem and development of leaves. Plant hormones control growth in the shoot apex.
