Lecture 3: Invertebrate Diversity Flashcards
1
Q
Structure: Growth and Skeletal Support
A
Unitary, Modular/colonial, Endo, Exo, Hydrostatic
2
Q
Modular/colonial
A
Individuals are made of similarly repeated structures/ units
3
Q
Hydrostatic
A
Skeletons made from enclosed fluid-filled compartments in whcih the fluid and epithelial can be rigid around fluid enclosed space to make a hydrostat
4
Q
Protosome features
A
Early gastrula, spiral cleavage, schizocoely (splitting of mesoderm for coelom formation)
5
Q
Deuterostome features
A
Ciliated blastula, radial cleavage, enterocoely (pocketing by archenteron for gut)
6
Q
Highly conserved features of development
A
Number of cells
Number of tissue layers
Type of body cavity
