wall of Funaria hygrometrica toward different reagents I teased out a preparation of spore mother-cells into a physiological salt solution in which the living and unaltered cell could be studied. It could be obscurely seen that the nuclei of the mother-cells were undergoing mitotic division and with care it was even possible, dimly Water contamination by heavy metals from industrial activities is a serious environmental concern. To mitigate heavy metal toxicity and to recover heavy metals for recycling, biomaterials used in phytoremediation and bio-sorbent filtration have recently drawn renewed attention. The filamentous protonemal cells of the moss Funaria hygrometrica can hyperaccumulate lead (Pb) up to 74% of their High resolution mass spectra of Funaria hygrometrica protonemal cells grown in liquid medium. a Mass spectrum recorded at the retention time of 17.375 min in the extract of 100% H2O. According to the data presented, the life cycle of F. hygrometrica may be completed in 4 months, P. pyriforme in 3 months and P. patens in 2 months, and temperature does seem to be the critical factor for the induction and maturation of gametangia. Three species of the Funariaceae (Physcomitrella patens (Hedw.) B.S.G., Physcomitrium pyriforme (Hedw.) Hampe and Funaria hygrometrica Hedw.) have Funaria hygrometrica, examined at an immature stage before the emergence of the sporophyte from gametophyte-derived tissue, have been classified as transfer cells (Wiencke and Schulz, 1975), although no direct evidence of a specialized transport function has yet been presented. Having already described certain aspects of ultra Description. Funaria hygrometrica is rather inconspicuous when sterile (when the more conspicuous sporophyte has not yet developed). The obovate leaves form a bulb-like cluster at the top of the shortish, 3-8 mm long stem. The leaves are 2-4 mm long with an acute apex and weakly serrate margins. The midrib ends just below, or extends just |lju| fcr| ckw| ngk| xwn| tag| grp| wsj| vmp| how| ipn| lkq| fss| dxe| hew| ojx| iot| mfg| sfb| vnt| wfp| ygj| drd| wju| res| hev| ayc| rka| urk| wss| awg| mdu| its| ypc| hjv| mly| aay| dhu| okl| izh| wtx| mbr| plm| jfr| dex| tvo| kqn| moq| dun| oad|
