A
petals
B
stems
C
guard cells
Explanation: 

Detailed explanation-1: -Xylem and Phloem tissues are present throughout the plant. They begin at the root and then move up to the stem, branches, and leaves. The xylem tissue transports water and minerals from the roots to the leaves whereas the phloem tissue transports food from the leaves to the other parts of the plant.

Detailed explanation-2: -Water Transport from Roots to Shoots The structure of plant roots, stems, and leaves facilitates the transport of water, nutrients, and photosynthates throughout the plant. The phloem and xylem are the main tissues responsible for this movement.

Detailed explanation-3: -The type of vascular tissue that transports water and minerals in plants from roots to leaves is phloem.

Detailed explanation-4: -After traveling from the roots to stems through the xylem, water enters leaves via petiole (i.e., the leaf stalk) xylem that branches off from that in the stem.

Detailed explanation-5: -Phloem: In the case of plants, the synthesized food is stored by various storage organs which include-stems, fruits, roots, etc. The vascular tissue, phloem helps in the transportation of the synthesized food from the leaves to various storage organs.
