How does water reach leaves from roots for photosynthesis?
Answer and explanation
Correct answer: Through xylem
Roots absorb water from the soil, mainly through root hairs. The xylem is the plant vascular tissue specialized for conducting water and dissolved mineral ions from roots toward stems and leaves. Cohesion, adhesion, root pressure, and especially transpiration pull help support this upward movement. Therefore A is correct. Phloem transports organic food, whereas alveoli and nephrons are structures of animal respiratory and excretory systems.
