What's the difference between pedicel and petiole?

Pedicel


Definition:

  • (n.) A stalk which supports one flower or fruit, whether solitary or one of many ultimate divisions of a common peduncle. See Peduncle, and Illust. of Flower.
  • (n.) A slender support of any special organ, as that of a capsule in mosses, an air vesicle in algae, or a sporangium in ferns.
  • (n.) A slender stem by which certain of the lower animals or their eggs are attached. See Illust. of Aphis lion.
  • (n.) The ventral part of each side of the neural arch connecting with the centrum of a vertebra.
  • (n.) An outgrowth of the frontal bones, which supports the antlers or horns in deer and allied animals.

Petiole


Definition:

  • (n.) A leafstalk; the footstalk of a leaf, connecting the blade with the stem. See Illust. of Leaf.
  • (n.) A stalk or peduncle.

Example Sentences:

  • (1) The results indicate that the anatomical counter-current heat exchanger is reduced or eliminated during heat stress by 'chopping' the blood flow into pulses, and the blood pulses are shunted through the petiole alternately by way of a switch mechanism.
