← Nature & AnimalsWhich outcome occurs when high soil salinity restricts osmosis?
A)Root pressure decreases significantly✓
B)Transpiration rate increases drastically
C)Phloem transport accelerates distally
D)Cohesion-tension theory becomes ineffective
💡 Explanation
When external salt concentration increases dramatically outside root cells, water exits the root via osmosis, leading to decrease in turgor that powers root pressure. Therefore, reduced root pressure occurs, rather than increased water transport, because the water potential gradient reverses under saline conditions.
