The document summarizes plant root structure and function. It discusses the main functions of roots including anchoring the plant, absorbing water and minerals, storing food, and propagating the plant. It describes the typical morphology of dicot and monocot root systems. It also explains the tissues that make up roots including the epidermis, cortex, endodermis, pericycle, and vascular tissues. Root modifications for storage, support, and absorption are also outlined.
