What's the difference between spadix and spike?

Spadix


Definition:

  • (n.) A fleshy spike of flowers, usually inclosed in a leaf called a spathe.
  • (n.) A special organ of the nautilus, due to a modification of the posterior tentacles.

Example Sentences:

  • (9) The single representatives of Actinomadura helvata, Actinomadura pusilla, Actinomadura roseoviolacea, Actinomadura spadix and Actinomadura verrucosopora seemed to form new centres of variation while Actinomadura citrea and Actinomadura malachitica showed much similarity with Actinomadura madurae.
  • (10) 14C02 production from [1-14C]-, [3,4-14C]-, and [6-14C]glucose, the detailed distribution of 14C from [1-14C]- and [6-14C]glucose, and the maximum catalytic activities of phosphofructokinase, fructose-1,6-diphosphate aldolase, glucose-6-phosphate dehydrogenase, and phosphogluconate dehydrogenase were determined at different stages in the development of the spadix.
  • (11) Oxidation of substrates was virtually all via the alternative oxidase, the cytochrome pathway constituting only 10-20% of the total activity, depending on the stage of spadix development.
  • (12) During later stages of spadix development, pyruvate oxidation was enhanced by the addition of aspartate.

Spike


Definition:

  • (v. t.) To set or furnish with spikes.
  • (v. t.) To fix on a spike.
  • (n.) A sort of very large nail; also, a piece of pointed iron set with points upward or outward.
  • (n.) Anything resembling such a nail in shape.
  • (n.) An ear of corn or grain.
  • (n.) A kind of flower cluster in which sessile flowers are arranged on an unbranched elongated axis.
  • (v. t.) To fasten with spikes, or long, large nails; as, to spike down planks.
  • (v. t.) To stop the vent of (a gun or cannon) by driving a spike nail, or the like into it.
  • (n.) Spike lavender. See Lavender.

Example Sentences:

  • (4) In this series there were 45 patients (40%) with independent focal interictal EEG epileptic abnormalities over frontobasal cortex (with or without independent spiking over interomedial temporal region).
  • (5) It was shown that gradual recovery of spike wave patterns occurred from initial water swallowing to successive dry swalllowing.
  • (6) One might expect that a similar news spike and rebounding of support for stricter gun control can happen, given President Obama's new push.
  • (7) By this action, oxytocin is believed to increase the probability of successful regenerative spikes and thereby initiate electrical activity in quiescent preparations, increase the frequency of burst discharges, the number of spikes in each burst, and the amplitude of spikes in individual cells.
  • (8) The differentiated neuroblastoma cell possesses characteristics of an electrically excitable cell and can generate propagated potential spikes in which Ca2+ is the inward charge carrier.
