Meristem cells are primarily located at the tips of the stem and roots, which is where they play a crucial role in the growth and development of the plant. These regions are known as apical meristems. The apical meristem is responsible for the elongation of the plant, allowing it to grow taller and expand its root system deeper into the soil. This growth is essential for the plant to reach more sunlight and water, which are vital for photosynthesis and overall health.

Other areas of the plant may contain different types of cells and tissues that support specific functions, but the primary activity of meristematic cells, such as cell division and differentiation, occurs at the growth points in the shoots and roots. This enables plants to grow continuously throughout their life, adapting to their environment and optimizing their structure for survival.
