WebbWhereas, the movement of phloem is bidirectional this is because, once the food is synthesized it is the phloem that transfers the food to all the parts of plants wherever it is necessary. So, movement of materials inside phloem is bidirectional, both upwards and downwards. So, the correct answer is option B.
