Down: 2) For feeding and defense4) Have body cavity, yet it is not completely lined with mesoderm. in example: Phylum Nematoda5) Collections of tissues performing a similar function6) have no body cavity. In example Phylum Platyhelminthes.8) Sea wasps, box jellies, medusa, are amont the venomous animals. 9) primarily marine. Have delicate silica skeletons. pseudopods extend outside the shells ot feed and move. 10) Flexible, in Amoebocytes11) body is plate or barrel shaped. has a top (oral) and a bottom (aboral). 2 tissue layers. in example Phylum Cnidaria & Phylum Ctenophora.12) The blastopore becomes the anus, in determinant cells. In example: Phylum Echnodermata, and Phylum Chordata. 13) (jellyfish)-primarily medusae14) digest and distribue food, produce skeleton. have spicules and collagen sponging. 15) Flowing extensions of cell membrane. Pseudopods used for locomotion and feeding on solid surfaces. Can be free-living or parasitic. 17) Euplectella-Silica spicules. a class of phylum Porifera18) (corals, anemones)-only plyps. can secrete CaCO3 skeletons that can from reefs. 20) maintain shape by hydrostatic skeleton. ability to change shape by contraction. primitive nervous system. 26) Highly differentiated collections of similar cells29) multiple unicellular organisms living together34) outer layer. covers the embryo surface, becomes the outer covering, nervous system. 37) most closely related to plants. Shallow intertidal. Single cells to multicellular. Muticellular-->Unicellular-->colonial40) provide support, CaCO3 or Si Across: 1) Have cilia for movement, feeding. usually soliary. Fresh water species. amont the most complex of all cells. 3) grow continuously (rotifers, flatworms, segmented worms, mollusks)7) must shed in order to grow (round worms, arthropods) 16) Have a large mitochondrion associated with a unique organelle called a Kinetoplast (contains extra-nuclear DNA). Blood parasites in example: Trypoanosoma17) Have a body cavity lined with mesoderm. Mesenteries connect inner and outer mesoderm layers and suspend organs in the coelem in example: Phylum Annelida19) Innermost layer. Lines the primitive gut, becomes the digestive tract, liver and lungs. 21) Cliona=Silica spicules or none at all. A class in Phylum Porifera22) Flagellatede, move and filter water (a.k.a collar cells)23) is the swimming, reproductive part in Phylum Cnidaria24) different cells specialized for different functions especially reproduction (gametes)25) middle layer, not in all animals. becomes muscles and internal organs27) alternate polyps and medusae, colonial 28) The simples protists, unicellular. heterotrophs (ingest ciliates). Internal cytoskeleton allows for amoeboid movement. Reproduce asexually by division. 30) the incomplete digestive tract part in Phylum Cnidaria31) Plankton, free-living flagellates. Two flagella produce spinning motion can produce toxins. Symbiotic in corals32) Animal parasites has apical complex-for penetration host. In example: Plasmodium=cause malaria. 33) Red accessory pigments absorb green light. Commerical uses. Shallow interitdal. Multicellular. Example Porphyra35) Attack cells that contain stinging organelles called nematocysts36) primarily aquatic, photosynthetic protists38) parasitic on land plants, can cause serious plant disease39) The blastopore becomes the mouth, In determinant cells. In example: Phylum molluska, Phylum Annelida, Phylum Arthropoda. consist of Lophotrochozoa & Ecdysozoa41) >9,000 species, 99% marine sessile: attached to substrate cellular level or organization. suspension (filter) feeders. No body symmetry. No digestive tract42) most are benthic, some are plankton. Calcium carbonated shells. Pseudopods extend through shells to feed and move. 43) Large multicellular, Typical "seaweed" examples: Sargassum and fucus. Thrives in nutrient rich water. Can grow up to 300 feet. (giant kelp)44) Grantia-calcium carbonate spicules. A class of phylum Porifera. 45) body has lengthwise axis, divides the body into 2 equal halves. considered adaptation for locomtion associated with cephalization. tissue layers in example: Phylum Arthropoda46) feeding part in Phylum Cnidaria47) many have chloroplast. can photosynthesize has an eye spot for sensing light. asexual reproduction only. for example: Euglena
