Andy's Bio 12
Show Answers:

  1. require moist environments for cycles.1) Mosses- most numerous; are mostly dioecious (seperate sexes)2) Liverworms- Flat, lobular appearance i.e. Marchantia3) hornwarts- hornlike sporophyte that grows up from a flattened gametophyte. Bryophytes have domminant gametophyte (haploid generation) and dependant (diploid) sporophyte generation Lack xylem; lack true roots, leaves, and stems
  2. Rhizopod
    type of protazoan like an amoeba
  3. Ciliata
    • the most highly evolved protozoans
    • posseses a micronucleus (repositiory for genetic info) and a macronucleus(contains some of genetic info found in the micro nucleus)
    • e.g. paramecium
  4. Chlamydiae
    Minute bacteria some cause infections in food tract
  5. Basidiomycota
    • -mushrooms
    • -in most an extensive underground hyphal mass sends up vertical hyphae fruiting bodies in which spores formed reproductive structure in fruiting bodies are club-shaped.
  6. There are 12 mammalian orders list 6
    • 1) cetacea- whales, dolphins
    • 2) Carnivora
    • 3) Rodenta- also beavers
    • 4) chiroplera- bats
    • 5) Artiodactyla- sheep cattle- even # of toes on each foot
    • 6) Perissodactyla- horses, rhinos- odd number of toes
  7. Pseudocoelomates
    Rotofers ( have fixed number of adult cells) and Nematoda (roundworks)
  8. some are heterotrophic, some photosynthetic
    Euglena-chloraplast membraneChloryphyll a and bswims using pair of flagellaeyespot helps it orient to light
  9. includes all eukaryotic unicellular speciesdivisions often based on functional characteristics
    Include: Protozoans (animal like)
    Algai Protists (Plant like)
  10. amoebas and their shelled relativesno cell wallI.E. Foraminetera- Most numerous of protazoas-amoebas w/ snail like shells -calcium carbonate shells (ocean)Radiolariam-shells rich in silicon (more resistent)
  11. Hairlike, single-cell processes that anchor gametophyte to the soil in bryophytes?
  12. Mammalian sub classes?
    • 3 Total:
    • 1) Protheria (monotremes)- lasck teeth, lay eggs, posses a beak. i.e. platypes, anteater
    • 2) metatheria ( marsupials or pouched animals) i.e. opossum
    • 3) Eutheria (true or placental mammals)
  13. Sporozoa
    • are all parasites
    • no locamotion
    • complex life cycles moving from one host to another
    • many gametes, spores produced
    • I.E.
    • Plasmodium- causes malaria
  14. -Probably the oldest living cells
    -lack peptidoglycan
    - branched lipids in membranes
    -no flagellum
    -generally extreme habitats
  15. consists of deuterosomes and protosomes
    -are all triploblastic (possessing 3rd laer mesoderm)
  16. lacks cell wall...?
    Unique among monerans
  17. Kingdom comprosed of single celled bacteria
    -lack nucleus or membrane bound organelles
    -posses ribosomes, DNA, and RNA
    -lack an ER
    Divided into two subkingdoms
  18. -Mesoderm arises from endoderm in the archenterm.
    -blastopore forms anus and mouth is formed secondarily
    Major Phyla
  19. Multicellular Female sex organ that prduces eggs.
    -Found in:
    Mosses, ferns, and conifers
  20. Present in all complex animals beyond the level of a roundworm
    -seperates the gut and the internal organs from the body wall (permits indep.Movement of these two sectors. Thus peristalic movements interior to coelan do not interfere with the cocmotor contractions of muscles in the body.
  21. extremely variable
    major groups are purple and green bacteria
    often has flagellum
    generally moderate
  22. -Compound eyes

    5 Classes
    1) Arachnida
    2) Crustacea- gills; i.e. shrimp, crab, barnacles have two pairs of antennae
    3) Diplopoda- Millipedes- herbivores, 2 pairs leggs per segment
    4) Chlipoda- Centepedes- carnivores
    5) Insecta- Most species
    -typically divided into 3 body part ( head thorax, and abdomen)
    Arthropoda and its classes
