lab 7 Flashcards
kingdom animalia characteristics
eukaryotic & multicellular
heterotrophic
lack a cell wall
composed of specialized tissues which arise from three germ layers
usually motile
diploid and reproduce sexually
animal symmetry
Sponges – lack symmetry; known as asymmetrical
Eumetazoans (animals w/ true tissues) – may exhibit radial or bilateral symmetry
cephalization
an evolutionary trend towards the concentration of sensory
structures (antennae, eyes, etc) at the anterior end of a bilateral animal
Sponges and Eumatazoans tissue
Sponges – composed of several cell types, yet lack organized tissues
Eumetazoans – animals with true tissues (germ layers); these germ layers give rise
to more complex tissues and organs as the animal develops
three germ layers
- endoderm – forms lining of the digestive tube
- ectoderm – forms the outer covering of an animal (& sometimes the
central nervous system) - mesoderm – produces muscle & remaining tissues & organs
Eumetazoans tissues
diploblastic – “2 tissues” – only develop endoderm & ectoderm
triploblastic – “3 tissues” – have mesoderm between the endoderm and
ectoderm
Triploblastic Body cavity categories
