Apical meristems are meristematic tissue found at the tips of roots and shoots that are responsible for root and shoot lengthening.
At the terminals of growing regions like roots and shoots, apical meristems are present.
The root apical meristem also called the root apex, is a small region at the root's tip where all cells may divide several times and all main root tissues are produced.
The root apical meristem is protected by the root cap, which is made up of living parenchyma cells, as it travels through the soil.
