In which structure does meiosis occur
Web1 dec. 2024 · Meristems are regions in plants in which mitosis takes place. Apical meristems are at the tips of shoots and roots and contribute to increases in length. Lateral meristems are responsible for increases in girth. Other meristems—intercalary, pericycle, fascicular—are zones of active mitosis and contribute to growth in various plant organs. http://www.waynesword.net/lmexer8.htm
