Solution

The correct options are
A Phloem is a conducting tissue.
C Phloem transport food.
D Xylem fibres provide mechanical strength.
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. On the other hand, phloem translocates food from leaves to the other plant parts. They have a bidirectional flow. Xylem comprises of tracheids, vessels, fibers, and xylem parenchyma. Whereas, phloem comprises of sieve tubes, companion cells, fibers, and phloem parenchyma. Xylem and phloem fibres provide mechanical strength.
