Protozoans are _____ in which movement of nutrients and gases is accomplished by ______
|
invertebrates, simple diffusion
|
|
|
Characteristics of Cnidarians
|
-cells are in direct contact w external or internal environment
-no specialized circulatory system -ex. hydra, coral, jellyfish |
|
|
Characteristics of arthropods
|
open circulatory system
-blood(interstitial fluid) in direct contact w the body tissues -blood flow thru dorsal vessel into sinuses where exchange occurs -ex, lobster, shrimp, insect, spiders |
