If food is being made in leaves how will roots get an energy source?
Answer and explanation
Correct answer: Phloem can carry food to the roots
Leaves produce sugars by photosynthesis, but roots also need chemical energy for absorption, growth, and respiration. Phloem transports soluble products of photosynthesis, mainly sucrose, from source regions such as leaves to sinks such as roots, fruits, and storage organs. Thus option A is correct. Xylem mainly carries water and minerals upward, while alveoli, urine, and stomata do not provide this food-transport route.
