Stele


Definition:

  • (n.) Same as Stela.
  • (n.) A stale, or handle; a stalk.

Example Sentences:

  • (1) The maximum catalytic activities of PFK (PPi) in apex, stele and cortex of the root of pea (Pisum sativum) and in the developing and the thermogenic club of the spadix of cuckoo-pint (Arum maculatum) were measured and compared with those of phosphofructokinase, and to estimates of the rates of carbohydrate oxidation.
