Q1. An experiment is designed to study mechanism of sucrose uptake by plant cells. Cells are immersed in a sucrose solution, and pH of the solution is monitored with a pH meter. Samples of the cells are taken at intervals, and sucrose in the sampled cells is measured. The measurements show that sucrose uptake by the cells correlates with a rise in the pH of the surrounding solution. The magnitude of the pH change is proportional to the starting concentration of sucrose in the extracellular solution. A metabolic poison known to block capability of cells to regenerate ATP is found to inhibit the pH changes in the extracellular solution. Suggest a hypothesis accounting for these results. Propose an additional experiment to test your hypothesis.

Q2. A researcher lyses a cell that contains nucleic acid molecules and capsomeres of tobacco mosaic virus (TMV). The cell contents are left in the covered test tube overnight. The next day this mixture is sprayed on tobacco plants. Which would be expected to happen?
