The Red List of plants and fungi in Poland was published by Zarzycki & Mirek (1996) and the Red Data Book appeared five years later (Zarzycki & Kaźmierczakowa 2001).

This can be confusing because members of the division Pteridophyta were also denominated pteridophytes (sensu stricto). Life forms interpreted as early animals were present in the Ediacaran biota of the late Precambrian. Many modern animal phyla became clearly established in the fossil record as marine species during the Cambrian explosion, which began around… If you would like to participate, please visit the project page, where you can join the discussion and see a list of open tasks. Whenever possible, books that are fully digitized for free access and/or download are referenced in this site with hyperlinks. Recent work both on their anatomy and on the morphology and structure of their spore-producing organs has however tended to show that their peculiarities can be best understood in the light of our knowledge of the Sphenophyllales. 1 2 3 4 The Incorrigible Children of Ashton Place Book 2: The Hidden Gallery Vydáno ve spolupráci s HarperCollins Childr ED/STV/2004/PI/15 Science Laboratory Technology National Diploma (ND) Curriculum and Course Specifications National Board FOR Technical Education Federal Republic of Nigeria Unesco Nigeria Project 2004
Smith System: Domain: Eukaryota • Regnum: Plantae • Divisio: Pteridophyta • Classis: Polypodiopsida Cronquist, Takht. & W.Zimm. Plants are mainly multicellular, predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, plants were treated as one of two kingdoms including all living things that were not animals, and all algae and fungi were treated… The phylogeny (evolutionary "family tree") of molluscs is a controversial subject. In addition to the debates about whether Kimberella and any of the "halwaxiids" were molluscs or closely related to molluscs, debates arise about the… The group includes fossils dating from 530 million years ago, in the Cambrian period. Thus some sources place horsetails in division Arthrophyta and ferns in division Pteridophyta, while others place them both in Pteridophyta, as shown below. The annelids (Annelida, from Latin anellus, "little ring"[a]), also known as the ringed worms or segmented worms, are a large phylum, with over 22,000 extant species including ragworms, earthworms, and leeches. Instead he found that various cydippid families were more similar to members of other ctenophore orders than to other cydippids.
Amoebozoa includes many of the best-known amoeboid organisms, such as Chaos, Entamoeba, Pelomyxa and the genus Amoeba itself. Certain fossils from the early Cambrian bear a striking resemblance to the velvet worms. These fossils, known collectively as the lobopodians, were marine and represent a grade from which arthropods, tardigrades, and Onychophora arose. Most families of entoprocts are colonial, and all but 2 of the 150 species are marine. A few solitary species can move slowly. The term haploid is used with two distinct but related definitions. In the most generic sense, haploid refers to having the number of sets of chromosomes normally found in a gamete. Because two gametes necessarily combine during sexual… Alternatively, members of Blastocladiomycota, Chytridiomycota, and Neocallimastigomycota lumped together as the zoosporic true fungi. The best-known Cercozoa are the euglyphids, filose amoebae with shells of siliceous scales or plates, which are commonly found in soils, nutrient-rich waters, and on aquatic plants.
Given that many of the sampled phylogenetic trees from the full data also contain polytomies, our estimates may be best considered conservative.
