|
|
Term
| Attaches cell cytoskeleton to collagen and other proteins in ECM |
|
Definition
|
|
Term
| Cell adhesion molecules (CAMs) |
|
Definition
Connects cells to one another
Determines the gap size between cells |
|
|
Term
| Junction that prevents materials in ECM from leaking between cells and prevents proteins in PM from migrating to other side of cell |
|
Definition
|
|
Term
| Junctions that bind cells tightly but do not prevent movement of material between cells or within cell membrane |
|
Definition
|

|
|
Term
|
Definition
| Organs radiate outwards; infinite lines of symmetry within a certain plane. |
|
|
Term
|
Definition
Definite anterior/posterior ends and dorsal/ventral ends

|
Term
| Sac-like digestive system |
|
Definition
One opening for food and excretion
Functions in circulation, gas exchange, and as a hydrostatic skeleton |
|
|
Term
| Limitations of the sac-like digestive system |
|
Definition
- Less specialization for ingetsion and excretion
- Less specialization for nutrient absorption and digestion
- Restricts animal to small size
|
|
|
Term
|
Definition
| Two openings: Mouth and anus |
|
|
Term
| Advantages of the tube-like digestion system |
|
Definition
- Allows for bigger organism
- Specialization: ingestion, absorption, excretion, digestion
|
|
|
Term
| Requirement of organism with tube-like digestive system |
|
Definition
| It must have evolved an exchange system, as cells are no longer in contact in nutrients |
|
|
Term
| Lacks body cavity surrounding organism |
|
Definition
|
|
Term
| Internal organs are not fully lined by mesoderm; body cavity is present |
|
Definition
|
|
Term
| Coelom present; tissue layer lines coelom and suspends internal organs (from mesoderm) |
