Definition of apical meristem : a meristem at the apex of a root or shoot that is responsible for increase in length First Known Use of apical meristem 1877, in the meaning defined above


apical meristem: a region of dividing tissue at the growing tips of roots and shoots that is responsible for increase in length of the plant body. MERISTEM cells are small, with thin walls and CYTOPLASM containing few vacuoles. They undergo active MITOSIS when growth is occurring (depending on the season) and the new cells look similar to the
