    Phylum: Porifera A sponge has differentiated cells and functionally distinct layers. The ameobocytes secrete spicules which stack up together to make the sponge. The choanocytes are composed of a flagellum and a collar (collar cells). The amoebocytes and choanocytes are the work force of the sponge--they create the body of the sponge. The major sponge groups of today had an ancestor in the Cambrian period. The sponges reproduce either sexually or asexually. When they reproduce sexually‚ they

    Designation of phylum cryptomycota within kingdom fungi Introduction The cryptomycota are considered to be to be an early branching clade of organisms‚ the only known members are species that belong in the genus Rozella (Lara et al 2010‚ Jones et al 2011‚ James and Berbee 2012). It has been suggested due largely to the amount of environmental sequences collected the phylum may be as diverse as the whole kingdom fungi (Jones et al 2011). While Rozella were originally placed in the fungal phylum Chytridiomycota(Jones

    to mosses (Phylum Bryophyta)‚ the vascular plant sporophyte is dominant over AND is functionally independent of the gametophyte. • Conductive (vascular) tissues are universal AND are present in the sporophyte (not the gametophyte). • Although mosses live in moist environments (at least some of the time)‚ some vascular plants have acquired relative independence of free water. • Some vascular plants survive in harsh conditions (including hot and cool deserts). Ferns belong to the Phylum Pterophyta

Starting out with a character matrix allows us to determine synapomorphies and apomorphies between theses two group‚ allowing us to construct the cladogram (Reece). My cladogram consisted of various phylums from the Animal Kingdom. The outgroup for my cladogram was the Choanoflagellates due to the fact that “they are the closest‚ living‚ unicellular relatives of animals” (Leadbeater). The phylum Prorifera has the ability to be asymmetrical and
