Document Summary
Chapter 16: 360 - see lecture 11 notes. Apical meristem: shoot and root tips continuously divide and produce the cells and tissues that mature into the tissues of the plant. Cork cambium: develops in stems and roots and produces a protective layer of cork tissue that replaces the primary epidermis. Primary growth: cells and tissues derived from the apical meristems. Secondary growth: cells and tissues derived from the secondary meristems. Vascular cambium: cylindrical meristem that produces xylem to the inside and phloem to the outside. Variety of concepts and theories to describe plants and apical meristems. Plants have indeterminate growth (just keep growing by production of new stems and leaves) Plants don"t usually reach a terminal growth stage. Plants are modular (producing new modules - stems and leaves) Plants are limited by disease environment (drought, res, frost) own success (too large to supply all parts)
