Is a sweet potato hydrophillic or hydrophobic

The sweet potato cells have a hydrophilic surface (because of the phospholipids on their cell membranes). But I don't think you can refer an object as hydrophilic or hydrophobic because an object can neither attract or repel water or oil, these stuffs usually happen in the molecular level:)

not the best question format lol but what i think might as scale color is controlled by a single gene with two alleles, the green allele and the yellow allele. when moths that are homozygous for green scales are mated with moths that are homozygous for yellow scales, 100% of the offspring have green scales.
