What's the difference between horsetail and spore?
Horsetail
Definition:
(n.) A leafless plant, with hollow and rushlike stems. It is of the genus Equisetum, and is allied to the ferns. See Illust. of Equisetum.
(n.) A Turkish standard, denoting rank.
Example Sentences:

(2) Isozymes of CuZn-superoxide dismutase (SOD) were purified from angiosperms (spinach and rice), fern (horsetail) and green alga (Spirogyra).
(3) The number of differences in amino acids between horsetail ferredoxins and other chloroplast-type ferredoxins indicated that the duplication occurred after divergence of horsetails from other plants.
(4) Two ferredoxins were isolated from horsetail (Equisetum telmateia) and their amino acid sequences were determined by use of a sequence analyzer in combination with carboxypeptidase digestion and manual Edman degradation of tryptic peptides of carboxymethyl-ferredoxins.
(5) Motile sperm of four ferns (Marsilea, Pteridium, Lygodium and Aneimia), a horsetail (Equisetum) and a liverwort (Marchantia) were fixed in the presence of tannic acid to visualise the dynein arms.
(6) A passenger resembling Ian, with a flat cap and a John Lennon moustache, snaps mobile phone photos of terraces lining the quarry walls, veritable hanging gardens with horsetail and eyebright.
(7) The visual inspection of the hay revealed a massive contamination (about 12% by mass) by horsetail.
(8) Axons of the basket cell type and "horsetail" axons associated with double bouquet cells of Cajal's original type were not impregnated.
(9) Some comments on the unique amino acid substitutions in horsetail ferredoxins are also presented.
(10) The mtDNA of Onoclea sensibilis (sensitive fern) is approximately 300 kb in size, while that of Equisetum arvense (common horsetail) is at least 200 kb.
(11) Amino acid sequences of amino-terminal regions of CuZn-SOD isozymes from spinach, rice and horsetail were determined and compared with those of CuZn-SODs from other plants.
Spore
Definition:
(n.) One of the minute grains in flowerless plants, which are analogous to seeds, as serving to reproduce the species.
(n.) An embryo sac or embryonal vesicle in the ovules of flowering plants.
(n.) A minute grain or germ; a small, round or ovoid body, formed in certain organisms, and by germination giving rise to a new organism; as, the reproductive spores of bacteria, etc.
(n.) One of the parts formed by fission in certain Protozoa. See Spore formation, belw.
Example Sentences:
(1) After absorption of labeled glucose, two pools of trehalose are found in dormant spores, one of which is extractable without breaking the spores, and the other, only after the spores are disintegrated.
(2) The dose response initially resembled that described by Scholer (1959) in which one million spores killed the majority of mice.
(3) Abnormal synaptonemal complexes were seen in all 19 crosses of N. crassa and N. intermedia that were examined, including matings between standard laboratory strains, inversions, Spore killers, and strains collected from nature.
(4) The mutant spores are pleomorphic and differ both in shape and size from the wild-type spores.
(5) The results presented here substantiate the hypothesis that in S. cerevisiae trehalose supplies energy during dormancy of the spores and not during the germination process.
(6) The fungicidal activity of six rabbit neutrophil cationic peptides (NP) against resting (dormant) spores, preincubated (swollen) spores, and hyphae of Aspergillus fumigatus and Rhizopus oryzae was examined.
(7) In the electron microscope large aggregates of beta glycogen particles were seen in the cytoplasm of sporoplasm cells in mature spores.
(8) The spore germination was synchronized by selection of the spores of the definite size and maintenance at a temperature of 0 degrees.
(9) GAD activity appeared in mutant spores after germination and increased to levels comparable to parent spores after 9 min of germination.
(10) The Ca++-form and H+-form spores of Clostridium botulinum 33A were investigated in vivo with respect to their water sorption and heat-resistance characteristics.
(11) Salt concentrations slightly lower than those providing inhibition tended to extend spore outgrowth time at low temperatures.
(12) The AL spores and the GN spores were morphologically distinct.
(13) Studies demonstrated the fact that there are present within the malignant cell and in the immediate area bacterial spores arising from one of several varieties of plant bacteria.
(14) The stages observed were diplokaryotic cells, sporogonial plasmodia, unikaryotic sporoblasts, and spores.
(15) The rod-shaped organism was motile, did not form spores, and had a gram-negative wall structure.
(16) Numerous factors influenced its activity: method of spore production, inherent spore resistance characteristics, alkalination, storage time and storage temperature.
(17) The inoculum level of infected spores in nutrient broth-yeast extract-glucose medium affected the transducing efficiency of SP-10 in lysates of these cultures.
(18) It can be dissociated from the spores using divalent metal chelators and will reassemble on the spores in the presence of calcium.
(19) Stable messenger ribonucleic acid (mRNA) was shown to be involved in both enterotoxin synthesis and synthesis of other spore coat proteins in Clostridium perfringens.
(20) Effects of alpha- or beta-D-glucose on the respiration of germinated spores (only germinated spores not including swollen spores and elongated spores) of Bacillus subtilis and B. megaterium were studied.
