The structure of Flowering Plants

the external
1. Roots
  1. Roots are found below Ground
  2. Function
    1. to anchor
    2. absorbs water
    3. stores food
  3. Types
    1. TAP ROOTS
      1. The primary roots
        lateral or secondary roots emerge from tap root
        tiny root hairs grow from lateral roots
        example- carrot
    2. FIBROUS
      1. roots form a mass of equally sized branched roots
      2. grows more shallow
      3. "hairy"
      4. example: grasses
    3. ADVENTITIOUS
      1. Roots that emerge from other parts of the plant
  4. Longitudinal Section of a root
    1. Protection: Root Cap
      1. proteccts root tip as it emerges from soil
    2. cell production: Meristem
      1. mitosis
      2. Apical Meristems located root and shoot tips
    3. elongation: plant growth regulators
    4. differentiation: Root hairs form. identical cells change to form new tissues
  5. Transverse Section of Root
    1. the new cells formed by meristems form 3 types of tissues
      1. 1. Dermal tissue: protective layer
      2. 2. Vascular Tissue: transport
        xylem carries water and minerals
        phloem carries food
      3. 3. Ground tissue
objectives
1. the external structure of a flowering plant
2. Classification of flowering plants
