   Show answer

   Answer: (4) Apical meristem

   उत्तर: (4) शीर्षस्थ विभज्योतक (एपिकल मेरिस्टेम)

   Apical meristems at the tips of roots and shoots contain actively dividing cells that increase the length of the plant body (primary growth). Collenchyma is a permanent tissue, and the cortex and the endodermis (the innermost layer of the cortex) are regions made of permanent tissue, so none of them is responsible for this growth.
