Which effect occurs when xylem differentiation fails in plant roots?

💡 Explanation

Reduced xylem tissue impairs water transport via transpiration pull, because water cannot efficiently reach photosynthetic tissues; therefore photosynthesis diminishes, rather than improving root function or herbivore defense which depend on sugar translocation.
