Morphology Notes 1

The document discusses the morphology of flowering plants. It covers the root system including types of roots like tap root and adventitious roots. It describes the functions of roots as absorption, anchorage, storage and synthesis of plant growth regulators. The regions of the root including the root cap, region of meristematic activity, elongation and maturation are also explained.
