The root apical meristem is a region of growth tissue near the tip of each root. The meristematic cells in this region grow in two directions, both backward toward the above-ground shoot and forward toward the tip of the root.
Meristems: There are 3 main types of meristematic tissue in vascular seed plants ---- apical, intercalary, & lateral meristems. Apical Meristem occur at the tips of roots and shoots and are responsible for the length-wise extension of the plant body known as primary growth.lants have 3 tissue systems --- ground, dermal, and vascular tissues. Plant tissues make up the main organs of a plant --- root, stem, leaf, & flower.
