Identify the types of transport happening in the pictures above. Compare and contrast these
2 types of transport. Include information such as direction of movements, energy usage, and
types of materials transported.
Claim:
Identify the type of transport happening in both pictures A and B. Be specific - If it is passive
transport, what kind (diffusion, osmosis, or facilitated diffusion)? If it is active transport, what kind
(endocytosis, exocytosis, or membrane pump)?
