Charac­ter­istics of Animals

eukaryotic
multic­ellular
lack cell wall
hetero­trophic
mostly sex reprod
diverse & complex develo­pmental strats
- gastru­lation, symmetry, germ tissue

animal body plans: tiss­ues

ectoderm
outermost covers embryos surface
endoderm
innermost, digestive tube
mesoderm
middle, connective tissues
 

animal phylogeny- 'body plans'

combine morpho­log­ical, molecular, fossil data
~ 35 animal phyla
body plan
set of morpho­logical and develo­pmental traits
 
symmetry, tissues, body cavaties

animal body plans: body cavities

coelomate
true coelom
pseudo­coe­lomate
"­fak­e" coelom
acoelomate
no coelom

General points of agreement

animals share a common ancestor
sponges are basal animals
eumetazoa clade with true tissues
most animals are bilate­rians
- 3 clades
 

animal body plans: gast­rul­ation

cleavage
rapid cell division in zygotes
blastula
embryonic stage of multic­ellular hollow ball from cleavage
gastrula
embryonic stage of dif. tissue layers created thru gastru­lation
blasto­pore:
opening on embryo.. usually becomes anus

protostomy vs deuter­ostomy

PROTOSTOMY
DEUTER­OSTOMY
mouth first
anus first
sprial determ­inate
radial indert­erm­inate
molluscs
chordates
