← ScienceWhich instability results when pressure exceeds cohesive molecular forces in the xylem?
A)Cavitation disrupts water column continuity✓
B)Plasmolysis lyses individual xylem cells
C)Lignification obstructs xylem transport
D)Osmotic pressure collapses phloem sieve
💡 Explanation
Cavitation occurs because water molecules separate when tension overcomes the cohesive molecular forces, which form hydrogen bonds and thus maintain water column cohesion. The breaks in the column disrupt water transport, leading to cavitation, rather than plasmolysis or lignification which affect cells directly.
