In very dry soils, the water potential (Yw) may fall below what is called the permanent wilting point, the water potential of the soil is so low that plants cannot regain turgor pressure even if all water loss through transpiration ceases. This means that

a) The hydraulic conductivity decreases drastically 

b) The water potential of the soil (Yw) is less than or equal to the osmotic potential (Ys ) of the plant

c) The water potential of the soil (Yw) is more than the osmotic potential (Ys) of the plant

d) cell osmotic potential (Ys) varies with plant species, the permanent wilting point is clearly not a unique property of the soil, it depends on the plant species

You have isolated a set of five yeast mutants that form dark red colonies instead of the usual white colonies of wild-type yeast. You cross each of the mutants to a wild-type haploid strain and obtain the results shown below;

y
