2. Transport in Animals
Can you describe transport in an ameba?.

3. Ameba –takes in H20 by osmosis and must be pumped out by contractile vacuoles.

4. Can you describe transport in hydras?

5. Hydra –Materials pass from cell to cell by diffusion through endoderm & ectoderm.

6. Can you describe transport in a grasshopper?

7. In a grasshopper –open circulatory system passes into sinuses from a tubular heart. Blood is colorless, does not carry O2.
Sinuses are open cavities between tissues.

8. Can you describe transport in an Earthworm?

9. Earthworm has a closed circulatory system similar to humans
Earthworm has a closed circulatory system similar to humans. Blood contains Hemoglobin which carries O2.

10. 5 Aortic arches pump blood to capillaries where diffusion into cells takes place.
