AP Taxonomy and Body Plans Crossword

Down:
1) The phylum that includes the tapeworms and flatworms.
2) members of a very diverse phylum, including such animals as gastropods, bivalves, octopuses, squids, cuttlefishes, and the chambered nautilus. 3) Referring to the head end of a bilaterally symmetrical animal.
5) a member fo the domain of prokaryotic microorganisms, distinguished from bacteria on molecular phylogenetic grounds and often found in hostile environments, such as volcanic vents and hot springs
7) The vertebrate class of bony fishes, characterized by a skeleton reinforced by calcium phosphate; the most abundant and diverse vertebrates.
8) organisms located in a central phyla that consist of the segmented worms9) multicellular organisms which have bodies full of pores and channels allowing water to circulate through them; commonly called sponges12) A member of a diverse phylum of animals that possess a notochord; a dorsal, hollow nerve cord; pharyngeal gill slits; and a postanal tail as embryos.
14) the differentiation of the anterior (front) end of an organism into a definite head. Considered an evolutionary advance, cephalization is accompanied by a concentration of nervous tissue (cephalic ganglion or brain) and feeding mechanisms in the head region that serves to integrate the activities of the nervous system.15) An organism formed by the symbiotic association between a fungus and a photosynthetic alga.
16) in human beings, toward the back, dorsal; in animals: toward the rear or tail: caudal; 20) A vertebrate possessing two pairs of limbs, such as amphibians, reptiles, birds, and mammals.
21) The opening of the archenteron in the gastrula that develops into the mouth in protostomes and the anus in deuterostomes.
23) make up a phylum of microscopic and near-microscopic pseudocoelomate animals. 24) Characterizing a body form with a central longitudinal plane that divides the body into two equal but opposite halves.
25) Pertaining to or situated near the back26) A body cavity completely lined with mesoderm.
29) A capsule in fungi and plants in which meiosis occurs and haploid spores develop.
34) Pertaining to the undersurface of an animal that holds its body in a horizontal position; to the front surface of an animal that holds its body erect.

Across:
4) The innermost of the three primary germ layers in animal embryos; lines the archenteron and gives rise to the liver, pancreas, lungs, and the lining of the digestive tract.
6) members of the mollusc class that includes octopuses, squids, cuttlefishes, ammonites, and the chambered nautilus.10) A taxonomic category above the kingdom level; the three domains are Archaea, Bacteria, and Eukarya.
11) Cartilaginous fishes; a class of aquatic, gill-breathing, finned vertebrates equivalent to the bony fishes 13) A vertebrate possessing an amnion surrounding the embryo; reptiles, birds, and mammals are amniotes.
17) the largest and most certainly the best-known Class of all the molluscs18) organisms that have a diverse forms as jellyfish, hydra, sea anemones, and corals. 19) The outermost of the three primary germ layers in animal embryos; gives rise to the outer covering and, in some phyla, the nervous system, inner ear, and lens of the eye.
22) marine organisms with internal, calcareous skeletons, five-part radial symmetry, and a water vascular system. Examples are starfishes, sand dollars, crinoids, and sea cucumbers. 27) A tubular excretory structure found in many invertebrates.
28) members of a phylum composed of the true round worms, many of which are parasitic.
30) A life cycle in which there is both a multicellular diploid form, the sporophyte, and a multicellular haploid form, the gametophyte; characteristic of plants.
31) A subdivision of flowering plants whose members possess one embryonic seed leaf, or cotyledon.
32) characterized by body hair and mammary glands that produce milk to nourish the young.
33) The formation of a gastrula from a blastula35) A member of one of two distinct evolutionary lines of coelomates, consisting of the annelids, mollusks, and arthropods, and characterized by spiral, determinate cleavage, schizocoelous formation of the coelom, and development of the mouth from the blastopore.
36) The evolutionary history of a species or group of related species.
37) One of two distinct evolutionary lines of coelomates, consisting of the echinoderms and chordates and characterized by radial, indeterminate cleavage, enterocoelous formation of the coelom, and development of the anus from the blastopore.
38) Characterizing a body shaped like a pie or barrel, with many equal parts radiating outward like the spokes of a wheel; present in cnidarians and echinoderms.
39) largest group of flowering plants40) The middle primary germ layer of an early embryo that develops into the notochord, the lining of the coelom, muscles, skeleton, gonads, kidneys, and most of the circulatory system.
