How do cells maintain water balance through osmosis?

Water then moves from cell to cell through the root cortex by osmosisalong a concentration gradient; this means that each cell is hypertonic to the one before it. In the centre of the root the water enters the xylem vessels. Water may move by diffusionthrough the cell walls and intercellular spaces.

The answer would be d because x,y = male and x,x = female so x,y is male so xxy is male with a female trait!
