  • root
  • The detached part of the plant remains physiologically active, allowing mitotic activity and new root structures to form for water and nutrient uptake. (wikipedia.org)
  • produce
  • Nuclear power plants use the heat generated from nuclear fission in a contained environment to convert water to steam, which powers generators to produce electricity. (ready.gov)
