If a potato is allowed to dehydrate by sitting in the open air, would the water potential of thee potato cells decrease or increase? Why?
potato water potential would decrease as water leaves the cells due to dehydration

Differentiate between active transport and facilitated diffusion, what makes them similar
Facilitated diffusion - does not require ATP - high to low concentration
Active transport - does require ATP - low to high concentration
Both require a protein
