Does Increased potassium ion concentration in the guard cells, make the guard cells a hypertonic or hypotonic solution?

Expert Answer:
The guard cells are turgid, or swollen, and the stomatal opening is large. This turgidity is caused by the accumulation of K+ (potassium ions) in the guard cells. This makes the guard cell solution hypertonic. As K+ levels increase in the guard cells, the water potential of the guard cells drops, and water enters the guard cells.
