Step 1
C Upwards and downwards in phloem
Answer
In plants, sugar is primarily transported through the phloem, which is responsible for the translocation of nutrients and carbohydrates. The flow of sugar in the phloem can occur both upwards and downwards, depending on the plant's needs and the season. This dual directionality allows the plant to distribute energy efficiently from sources like leaves, where photosynthesis occurs, to other parts such as roots and flowers.
