Botany modified plants

  1. rhizomes
    underground horizontal stems that allow vegetative spread and protection form the aboveground environment
  2. succulent stem

  4. stems have vascular tissues in a ring or scattered; roots have them in the center
  5. stem growth is often discontinuous; 
    root growth is relatively continuous
  6. stems are relatively impermeable to water; 
    roots are relatively permeable
  7. stem branches arise from axillary buds; root branches arise from the pericycle
  8. stems have nodes and internodes; roots do not
  9. leaves and axially buds are borne in regular patterns on the stem; branch roots are not
  10. monocots
    • orchids
