Which process limits water transport when desert plant roots encounter saline soil?

A)Reduced osmotic water potential
B)Increased photosynthetic water demand
C)Enhanced xylem vessel cavitation
D)Decreased stomatal transpiration rates

💡 Explanation

When soil salinity increases, the osmotic water potential outside the root decreases, causing less water to enter the root by osmosis; because water entry is limited osmosis, therefore the osmotic water potential is reduced rather than increasing other effects.
