| Characteristics of Animals |
|
Definition
multicellular eukaryotes
lack cell walls - greater morphological diversity
bodies have structural protien
specialized cells
Sexual reproduction |

Term
Choanoflagellates are closely related to animals
|
|
Definition
1) choanoflagelletes cells are similar to collar cells in sponges
2) collar cells found in animals, but not in choanoflagelletes protist plants
3) DNA Sequencing data shar high sequence similarity for specific signalling and adhesion

Definition
spiral and derterminate
cells are at an angle
2 masses of mesodermal cells migrate and form coelem
first mouth blastopore becomes mouth |
|
|
Term
|
Definition
radial and indeterminate
mesodermal cells bud off from archenteron and migrate to form coelom
second mouth, blastopore becomes anus
