Webb21 juni 2024 · The phloem’s main function is to transport the nutrients necessary for the optimal development of the plant, while the xylem is mainly responsible for transporting water and mineral salts. The phloem transport system works bi-directionally, transporting nutrients throughout the plant. In the case of xylem, this is unidirectional. WebbThe cell cannot function without certain organelles and must rely on the organelles of the companion cells. The companion cell is responsible for all metabolic functions of the sieve tube member. The companion cell is essential for the survival of the sieve tube member. This will cause the member to cease phloem function and kill the plant.

WebbPlants have transport systems to move food, water and minerals around.
