lab quiz 2 Flashcards
(32 cards)
characteristics of all animals
multicellular, eukaryotic, lack cell wall, heterotrophic
parazoa
no true tissues
eumetazoa
2-3 tissues
diploblast
2 tissues
endoderm
gut, liver, lungs; lining on the innermost layer of the organ or structure
mesoderm
skeleton, muscle, kidney; the middle layer of an embryo in development
ectoderm
skin, nervous system; the outermost layer of tissue in development
bilateral symmetry
animals cut into the left and right
radial symmetry
animals can be cut any way with multiple mirrored halves
tripoblast
forms a tubular gut tube during the blastocyst stage
protostomes
first mouth; mouth develops first in embryo growth
deuterostome
second mouth, anus forms first
coelom
interior body cavity lined with mesoderm in between the ecto and endo derm
psuedocoelom
the ectoderm is lined by mesoderm and the inner cavity is around endoderm
acoelomates
the body cavity has been lost and filled with mesoderm tissue
ecdysis
the process of shedding the old skin or casting off the outer cuticle
lophotrochozoa
monophyletic group of animals that includes: molluscs, annelids, platyhelminthes and others, all bilateral animals
cellulase bioassay
tests the presence of cellulase in the growth, if stained will avoid stain when none is present
protease bioassay
the agar will turn transparent if protease is present, no staining is needed
amylase bioassay
staining will clarify where amylase is present, where the lugol’s stain clears up signifies where amylase is
angiosperms
plants with flowers that attract pollinators into the center and eventually develop fruit
stamen
male reproductive plant parts
filament
the stem of the stamen
anther/stigma
the male reproductive parts of the plant, the top of the stamen
