Answer 1

Answer: (A)

Apoplast and symplast are two routes used by plants to transport water from root hair cells to the xylem of the root. Apoplast includes the non-living components of a plant such as cell walls and the intracellular spaces. The main difference between apoplast and symplast is their mechanism of the water movement.
