What's the difference between pollinium and polyad?
Pollinium
Definition:
(n.) A coherent mass of pollen, as in the milkweed and most orchids.
Example Sentences:
(1) These results indicated that Zea pollinium could inhibit formation of lipid peroxidates, protect the structure and function of erythrocyte membrane from the injury of peroxidate.
(2) In this paper, the effect of Zea pollinium on the structure and function of erythrocyte membrane in rats was observed.
(3) Retinaculum spans the lateral blade of the corpusculum to the acellular beak of the pollinium.
(4) The contents of sulfhydryl and sialic acid were also increased, but the content of MDA was markedly decreased with the use of Zea pollinium.
(5) 12 male rats were divided randomly into pollen and control groups, the former was fed with diet containing 10% Zea pollinium; while no pollen for the latter.
Polyad
Definition:
Example Sentences:
(1) Implications are indicated in polyadic systems, and a new aspect of transference is noted.
(2) Pollen of acacias is transported by insects as polyads, composite pollen grains.
(3) This defect correlates with several abnormalities in subsequent developmental events including the formation of multinucleate daughter cells, multiple microspindles during meiosis II, multiple phragmoplasts, polyads of microspores, and cytoplasmic microtubule foci.
(4) The polyad has enough pollen grains to fertilize all ovules within a flower and hence all seed within a pod may be full sibs.
(5) A series of experiments has been carried out with single doses of simple analgesics in patients with rheumatoid arthritis using a consistent polyad design.
(6) The following main anomalies of meiosis were revealed: the univalent state of chromosomes; an irregular movement of 8 to 33 chromosomes to the poles; the lag of 6 to 25 chromosomes and their premature splitting into chromatids; formation of micronuclei in diads and tetrads, formation of polyads.
