Answer:
It transports food to all the parts of the plant both upwards and downwards is the correct answer.
Explanation:
Phloem is tissue present in plants that transport the food prepare in the leaves to other parts of the plant.
Phloem has various types of specialized cells such as parenchyma cells, sieve elements, sclerenchyma, and companion cells.
Phloem transfers the food from source(leaves)to sink(to the other parts of the plant's cells), and in the spring process get reversed as the food stored in the sink move towards the developing buds through the phloem that's the reason phloem transports food to all the parts of the plant both upwards and downwards and movement of food is bidirectional.
