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. They are autotrophic eukaryotes, which means they have complex cells, and make their own food. Usually they cannot move (not counting growth).

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.
A pteridophyte is a vascular plant (with xylem and phloem) that reproduces via spores, and therefore was a member of the former and now
