What's the difference between desmid and unicellular?
Desmid
Definition:
(n.) Alt. of Desmidian
Example Sentences:
(1) Motility of the desmid Cosmarium cucumis depends on light: switching the light on induces a large fraction of previously immotile cells to start moving, and switching it off causes many motile cells to stop.
(2) Bacteria (cocci, rods, spirochetes, purple bacteria and cyanobacteria), detritus, euglenoid protozoans and algae (desmids and diatoms) comprised the majority of particulate food, in order of abundance; other protozoans were rare, and hyphal forms (actinomycetes and fungi) were not observed.
(3) Cosmarium turpinii, a fast-growing desmid alga, transforms into protoplasts in 4 h when incubated in a mineral medium + 0.4 M mannitol + 0.5% Cellulysin.
(4) Observations on lobe growth in the lateral wings of the developing primary cell wall in the desmid Micrasterias rotata are reported and discussed.
Unicellular
Definition:
(a.) Having, or consisting of, but a single cell; as, a unicellular organism.
Example Sentences:
(1) Dunaliella bardawil, a unicellular green alga that can be induced to accumulate massive amounts of beta-carotene, is particularly suitable for studies of carotenogenesis regulation and its links to developmental and adaptive processes in the chloroplast.
(2) Statistical analysis of 251 phylogenetically informative nucleotide positions rejects the "volvocine lineage" hypothesis, which postulates a monophyletic evolutionary progression from unicellular organisms (such as Chlamydomonas), through colonial organisms (e.g., Gonium, Pandorina, Eudorina, and Pleodorina) demonstrating increasing size, cell number, and tendency toward cellular differentiation, to multicellular organisms having fully differentiated somatic and reproductive cells (in the genus Volvox).
(3) Free amino acid pools were examined for cultures of vegetative cells, gametes, and mature zygotes of the unicellular green alga Chlamydomonas reinhardtii (Dangeard).
(4) Cyanelles are photosynthetic organelles which are considered as intermediates between cyanobacteria and chloroplasts, and which have been found in unicellular eukaryotes such as Cyanophora paradoxa.
(5) Six unicellular strains from these habitats and Synechococcus strain PCC 7942, a strain maintained for more than 10 years under laboratory conditions, were assessed for ingestion and digestion by larvae Culex pipiens and Anopheles gambiae mosquitoes.
(6) Gene rearrangements altering gene expression have mainly been found in some unicellular organisms.
(7) The flagellates and the ciliates have long been considered to be closely related because of their unicellular nature and the similarity in the structures of the axoneme of the flagella and cilia in both groups.
(8) The monoclonal antibodies did not recognize type I or type II cAMP-dependent protein kinase from rabbit muscle nor did they cross-react with proteins from several unicellular eucaryotes, with one exception: antibodies specific for the catalytic subunit recognized a 40-kDa protein of Tetrahymena pyriformis.
(9) Cleavage occurred at random after 23s rRNA formation and was stimulated by light in this organism, an obligately photoautotrophic unicellular blue-green alga.
(10) The data on the quantity and quality of protein from the unicellular algae are indicative of its high biological value and applicability to BLSS.
(11) Primary interaction of TSH with the unicellular Tetrahymena accounted for an increase in TSH binding capacity on reexposure, i.e.
(12) Nineteen plaque-forming viruses of the unicellular, eukaryotic Chlorella-like green alga, strain NC64A, were isolated from various geographic regions in the United States and characterized.
(13) Chlamydomonas reinhardtii is a unicellular eukaryote whose light-tracking system consists of a single eye.
(14) independence of ambient temperature, was found for ultradian rhythmicity even at the level of the unicellular organization.
(15) Unicellular planktonic algae show considerable developmental plasticity in relation to mean cell size and the fraction of the cell volume occupied by various organelles.
(16) Substituting size-fractionated silica particles for diatoms (the fossilized cell walls of unicellular algae) allowed for the purification of microgram amounts of genomic DNA, plasmid DNA, and rRNA from cell-rich sources, as exemplified for pathogenic gram-negative bacteria.
(17) When the sequence is compared with that from the plastocyanin of the unicellular green alga Chlorella fusca, the French-bean protein shows the deletion of the N-terminal residue, a two residue insertion and 53 identical residues.
(18) The unicellular conjunctival mucous glands secrete both neutral and acidic glycoconjugates as shown by positive reactions with PAS, PAPD, PAPS, and AB methods.
(19) Each equation is modified as necessary to conform to the three current models for sodium, chloride, and bicarbonate secretion: (1) "exchange-diffusion," (2) "two-component," and (3) "unicellular" models.
(20) Cells of unicellular cyanobacteria of typological group Ia, containing approximately 50 mol% guanine + cytosine (G+C) in their DNA (R. Y. Stanier, R. Kunisawa, M. Mandel, and G. Cohen-Bazire, Bacteriol.
