Document Summary

Meristems: regions a permanent growth where cells actively divide: apical meristems: meristematic tissues found at or near the tips of roots and shoots. Roots increase in length as the apical meristem is producing new cells (1) tissues here are called primary tissue: lateral meristems: produce tissues that increased the girth of roots and stems. Tissue produced here is called secondary tissue as it is produced after the primary tissue has matured. Differentiation: the process by which a cell becomes specialized for particular function. Determinants growth: growth that stops at a predetermined point in an organism"s. Indeterminant growth: growth that continues until death development. Dermal tissue: primarily on the outside of a cell, it exclusively protects against desiccation and external agents like pathogens. Vascular tissue: adapted for primarily physical support and translocation of materials within the cell. Ground tissue: most varied in function and form, but generally associated with the functions of synthesis and accumulation of organic compounds.
