Animal Taxonomy and Phylogeny Flashcards
What are the four types of body symmetry?
- Spherical symmetry
- Radial symmetry
- Bilateral symmetry
- Biradial symmetry
What are the planes of symmetry
- transverse plane
- frontal plane
- sagittal plane
divides the body into anterior and posterior (front and back)
a. transverse plane
b. frontal plane
c. sagittal plane
a. transverse plane
divides the body into dorsal and ventral (up and down)
a. transverse plane
b. frontal plane
c. sagittal plane
b. frontal plane
vertical plane which passe through the body longitudinally, divides the body into a left and right section
a. transverse plane
b. frontal plane
c. sagittal plane
c. sagittal plane
blastopore becomes mouth
a. protostomes
b. deuterostomes
a. protostomes
blastopore becomes anus
a. protostomes
b. deuterostomes
b. deuterostomes
two germ layers
diploblastic
two germ layers + mesoderm
triploblastic
has gut tube, mesoderm and coelom
a. coelomate
b. acoelomate
c. pseudocoelomate
a. coelomate
has gut tube and mesoderm
a. coelomate
b. acoelomate

Blastopore becomes mouth
a. diploblastic
b. triploblastic
b. triploblastic
Blastula -> Gastrula only
a. diploblastic
b. triploblastic
a. diploblastic
a common feature of metazoans
a. gills
b. metamerism
b. metamerism
serial repetition of body segments; longitudinal axis
a. metamerism
b. setae
a. metamerism
contains internal and external structures, for mobility and complexity of structure and function
a. epithelial tissue
b. metamere or somite
b. metamere or somite
a sheet of cells that covers an internal or external surface of the animal body
a. choanocyte
b. blastopore
c. epithelial tissue
c. epithelial tissue
Epithelial tissue
Internally-
Externally -
Epithelial tissue
Internally- lining for all organs and ducts as well as all passageways
Externally - used for protectuon
Single squamous epithelium, simple cuboidal epithelial, single columnar epithelium
simple epithelia
transitional epithelial tissue that allows great stretching
stratified epithelium
is widespread in body but contains relatively few cells, many fibers, and a ground substance or matrix that suspend fibers
a. epithelial tissue
b. connective tissue
c. nerve tissue
b. connective tissue
two types of connective tissue proper occur in vertebrates
loose connective tissue and dense connective tissue
Other specialized connective tissues include blood, lymph, adipose tissue, cartilage
wala na ayan na sagot
semi-rigid tissue of firm matrix cells (chondrocytes) with collagen and elastin
a. cartilage
b. bone
a. cartilage
