BiologyCell: The Unit of LifeNEET

NaCl is harmful to most crop plants. A scientist at the University of Toronto genetically modified a plant so that it could be grown in dry parts of the world where the available water has a high level of NaCl. This genetically modified plant copes with the high levels of NaCl by transporting salt into its vacuoles where it accumulates to abnormally high levels. Which feature would be observed in a genetically modified plant when compared to a non-modified plant?

Answer: (D)

Solution

Since the vacuole now holds abnormally high salt levels and has a very low (more negative) water potential, the cytosol must also raise its solute concentration (via compatible, non-toxic solutes) to
