Plant physiology questions
To be completed and turned in next week: POST-LAB QUESTIONS: 1. If a potato core is allowed to dehydrate by sitting in the open air, would the water potential of the potato cells decrease or increase? Why? 2. If a plant cell has a lower water potential than its surrounding environment and if pressure is equal to zero, is the cell hypertonic (Gn terms of solute concentration) or hypotonic to its environment? Will the cell gain or lose water? Explain 3. What would happen if you applied saltwater to the roots of a plant? Why? 4. Will water move into or out of a plant cell if the cell has a higher water potentfal than the surrounding environment? 5. What is the solute concentration of both the potato?
To be turned in next week Are there quantitative differences in protein concentration between the plant samples? Why? Are there qualitative differences between the plant samples? If the protein profiles are different, why? Lastly, in some samples you should observe a big band representing a protein in great abundance. The size of this protein is around 50 kDa. This protein is present in tissue. What is the name of this protein and what is its function? (For this question, you will need to do some digging...) tissue but not
