Growth elongation refers to the process by which a plant or organism increases its length or size through the expansion and division of cells in its tissues. This growth typically occurs in specialized regions called meristems, located at the tips of stems and roots. These meristematic cells continuously divide and differentiate, leading to the elongation of the plant or organism. Growth elongation plays a crucial role in the development and expansion of various plant structures, such as stems, leaves, and roots.
