WebJun 8, 2024 · Primary growth is a result of rapidly-dividing cells in the apical meristems at the shoot tip and root tip. Subsequent cell elongation also contributes to primary growth. The growth of shoots and roots during primary growth enables plants to continuously seek water (roots) or sunlight (shoots). WebCell division in plants is concentrated in meristems, although plants are unusual in that mature cells can return to cell division under the right conditions. Shoot and root apical meristems are already organized in the embryo of the seed. The root apical meristem (RAM) is the simpler of the two apical meristems. The dividing cells are just a ...
