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

Phylum Echinodermata: Five main groups of echinoderms including brittle stars‚ starfish‚ echinoids‚ sea cucumbers‚ and sea lilies are individually sexed. Sexual reproduction is common because both males and females are present. It takes a few years for echinoderms to mature and get sexually mature. Echinoderms do not require physical contact for the exchange of reproductive material instead they typically release their sperm and eggs into the water. Millions of individual sperm and

Animal Phylum Poster/Display Project Each student will select a major group of animals to research and ultimately create a poster or display to help explain the group of animals belonging to each class. Be sure to first read your textbook on the group as well as consult general resources before getting into specific resource materials. Students will be graded primarily on the content of the information as well as the creativity of the poster or display. The entire project is worth 75 points

Stinson‚ Margie Biology 210 Lab Questions: Phylum Annelida You will learn the answers to most of these questions in class and in lab. Great resource: http://www.bumblebee.org/invertebrates/ANNELIDA.htm 1. What does the word annelida mean? 2. Recall‚ some of the nematode worms appeared superficially to have external rings. Describe true segmentation in annelids. How is the true segmentation in annelids differ from having rings around the ectoderm as in nematodes? 3. What two layers

CHAPTER 12: MOLLUSCA Mollusca is an enormous taxon 2nd only to Arthropoda in number of living species Includes many familiar animals such as snails‚ clams‚ oysters‚ mussels‚ slugs‚ octopods and squids in seven lining classes Mollusca includes the taxa: Aplacophora consists of small‚ wormlike molluscs w/ numerous calcareous spicules rather than a shell. Polyplacophorans or chitons have eight shell plates Monoplacophorans have a low‚ conical‚ limpetlike shell and live in deep water

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

characteristics and evolutionary change between two phylums. 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
