If xylem gets blocked, why can photosynthesis decrease in leaves?
Answer and explanation
Correct answer: Less water and minerals will reach leaves
The governing concept is transport of raw materials for photosynthesis. Xylem carries water and dissolved minerals upward from roots to stems and leaves. Water is a reactant in photosynthesis, and mineral ions support chlorophyll formation and enzyme activity. If xylem is blocked, the leaf receives less water and minerals, so photosynthetic food production may fall. Thus option A is correct; phloem transports food, while the other choices concern unrelated animal functions.
