1 one of the advances vital to the evolution of the amniote egg was the development of four _ _ _s, the yolk _ _ _ , amnion, chorion and allantois, which nourish and protect the embryo and interface with the exterior environment 5 the fertilized egg 8 blas_o_eres are cells formed during cleavage; a fla_wor_ is acoelomate 9 the Dictyostelium slug, formed by myxamoeba that begin to synthesize, secrete and respond to cAMP upon a starvation signal 11 the _ _ino acid sequence directly reflects the DNA sequence in prokaryotic but not in eukaryotic chromosomes 12 ___ (touch) is required for cells to adhere and form multicellular entities; e.g., ___ between starved myxamoebae allows the cells to stick to each other because starved cells are stimulated to synthesize new cell adhesion molecules 14 the mesoderm l_n_s the body cavity in coelomates 16 development is dyn_ _ _ c; the embryo changes dramatically as it goes through sequential developmental stages 17 multicellular animals that pass through embryonic stages of development 21 likely stimulated by cAMP to differentiate in Dictyostelium, this cell will disperse to form free-living individual myxamoeba 22 overseer, supervisor 23 organogenesis begins as the ectoderm gives rise to the neural ___, which in turn will form the brain and spinal cord 25 yes, Spanish 27 the nuclear membrane allows eukaryotes to _ _gulate which transcribed genes will make protein 28 second letter, Greek 30 type of control in which a developmental or environmental signal will cause synthesis of mRNA that the cell had not synthesized before 36 hint 37 the _ _cheocyte is a sponge cell that can generate all the other types of sponge cells 38 what you do with your textbook 39 protein that wraps and organizes eukaryotic DNA, helping to regulate which genes are expressed in which cells 42 during cl_ _vage, the zygote divides without growth to form a blastula composed of many small cells; DNA and amino acid sequences are colin_ _ar in prokaryotes but not in eukaryotes 43 the _ _ l _ supplies nutrients for embryos that develop in the amniote egg 45 mesoderm is _ _dimentary in the Radiata 46 in _ _ogamous sexual reproduction, the haploid gametes are similar in size, shape and motility 49 the _ _ _ _ _ _ _ia include deuterostomes and protostomes; the group gets its name because in all species within the group, the left and right sides are mirror images of each other 53 acoelomates have __ body cavity; Parazoa have __ germ layers; prokaryotes have __ nucleus 54 during prokaryotic division, daughter chromosomes attach to adjacent points on the cell membra_ _ which grows and separates the chromosomes 55 this outer germ layer formed during gastrulation; it will generate the nervous sytem and epidermal cells 60 ___ cells are set aside from the somatic cell lineage for future reproduction; the ___ layers form during gastrulation 63 is, for plural nouns 64 concept, scheme, strategy 66 abbreviation for a chemotactic substance that causes Dictyostelium myxamoebae to stream together to form a grex 67 forms pouches during enterocoelous formation of the body cavity; forms a solid block that is hollowed out during schizocoelous formation of the body cavity TOP |
1 step on heavily and repeatedly, trample 2 the ___ is a fluid-filled sac that surrounds and protects the embryo in an amniote egg 3 the so_ _ _ _ of the neural tube is the ectodermal germ layer; the so_ _ _ _ of the body cavity in coelomates is the mesoderm; a so_ _ _ _ of diffusible cAMP is the myxamoebae in Dictyostelium 4 s_ _ual reproduction, a combining of genes from different individuals, can be independent of cell division: e.g., bacteria exchange genes through sex pili; paramecia exchange genes during conjugation 6 an environmental or developmental signal can cause cells to ___ (acquire) new properties; e.g., starved myxamoebae transcribe new genes to synthesize cAMP and cell adhesion molecules 7 nucleos_ _ _ _ are formed by histones; ribos_ _ _ _ translate DNA in prokaryotes and eukaryotes; protost_ _ _ _ gastrulate by forming the mouth first; duoterost_ _ _ _ include the chordates and echinoderms 9 sperm and eggs 10 b_ _ _er; superior, preferable 12 Gonium is a ___ (example) in which identical cells have rapidly undergone ordered divisions without growth to generate an organized cellular array, becoming a flat plate of cells. 13 in _ _ _ _translational control, the ability of a protein to function can depend on its being linked with other proteins; the _ _ _ _erior cells in a grex are prespore cells that will form the next generation of myxamoeba 15 type of symmetry that typifies jellyfish, corals, hydras and comb jellies 18 if you remove the rhyzoid from Acetabularia, it is _ _ l _ (has the capacity) to regenerate a new cap, despite the loss of its nucleus, by using mRNA stored in the stalk 19 the meta_ _a are multicellular animals ranging in complexity from simple flatworms to people 20 during g_ _trulation, the three germ layers emerge, the ectoderm, mesoderm and endoderm 24 an inability for a woman to have children is sometimes refered to as being _ _ _ _ _n 25 portion of a Dictyostelium fruiting body that will die 26 in Dictyostelium, cells in a ___ body differentiate to form two alternative cell types, stalk cells or spore cells; the ___ body is also an example of morphogenesis since individual cells organized to form its cohesive structure 27 _ _A polymerases transcribe DNA to make _ _A in both prokaryotes and in eukaryotoes 28 in Dictyostelium, the grex forms after amoeba are starved; it migrates into the light where it differentiates to form a fruiting ___ that will produce spore cells that in turn disperse to form new myxamoeba 29 the _ _doderm is the innermost germ layer; a nuclear _ _ velope characterizes all eukaryotes; ribonuclease is an _ _zyme; in _ _terocoelomates the body cavity develops from mesodermal pouches that extend from the gut 30 word for what your instructor will do, but without vowels 31 infants without B's, plural 32 flagella of Chlamydomonas ___ (are able to) adhere at their tips if the cells are of opposite mating types 33 cells fated to form myxamoeba lie in the posterior 4/5ths of a fruiting body in Dictyostelium; they are elevated to the tip of the fruiting body by the stalk cells 34 a hot or iced drink 35 colon_ _l eukaryotes are collectively called Volvocaceans; Cnidar_ _ns such as the jellyfish are Radiata 40 in _ _ _nscritional control, a signal causes synthesis of novel mRNA; _ _ _nslational control governs which mRNA is translated; in post_ _ _nslational control, proteins are made but are inactive until linked with other proteins 41 eukaryotes can regulate which mRNAs are translated by regulating which are passed ___ (a preposition) of the nucleus into the cytoplasm 44 cell adhesion molecules would be found __ (a preposition) flagella of Chlamydomonas during mating 47 the _ _ _stalk cells lie in the anterior portion of the grex; if these are removed, cells that would normally form _ _ _spore cells will regulate, change their fate, and develop into stalk cells 48 in _ _ _ _ _y, one mating type produces large, relatively immotile eggs while another produces small, motile sperm 50 the blood-sucking parasite, the _ _ _ _h, is a protostome 51 both the protostomes and the deuterostomes have thr_ _ germ layers during development; in h_t_rogamy, a species forms swiming gametes of different sizes 52 radial cleavage (abbrev) is typical of deuterostomes 56 precede with BAN to be petite; end with PER to fiddle 57 a _ _ _cendant is a child or offspring 58 to free from something undesirable 59 insert an O for fashion, an A to create 61 the _ _diata have only a few mesoderm cells that lie in a gelatinous matrix 62 intermix with EO for a note, with IE for one who mimics 65 the disposition of mesod_ _m characterizes different metazoan groups; it is absent in parazoa, sparse in Radiata, and present in Bilateria |
