Detailed explanation-1: -Detailed Solution. The correct answer is Phloem transports photosynthetic products. Phloem is a living tissue in vascular plants that conducts the soluble organic compounds synthesized downwards from the leaves during photosynthesis. Hence option 2 is correct.
Detailed explanation-2: -Xylem does not help in the transport of photo sent its or sugars. Instead, it helps only in the transport of water and minerals. Therefore, the first statement is not true.
Detailed explanation-3: -Vascular tissue in plants comprises of xylem and phloem. Both are conducting tissues. Xylem transports water and minerals from root to other parts of the plant. They have a unidirectional flow.
