Solution

The correct option is A Statements X, Y and Z are true
The simple sugar produced by plant is converted into complex sugar, starch and is stored in roots. Plants have two types of transport tissue. Xylem transports water and mineral from the roots to the leaves. The direction of movement is unidirectional. The phloem transports food from the leaves to the different parts of the plant. The direction of movement of phloem sap is bidirectional.
Thus, the correct answer is 'Statements X, Y and Z are true.'
