Detailed explanation-1: -Veins of the leaves contain conjoint and colateral vascular bundles, hence contain both xylem and phloem.

Detailed explanation-2: -These are located in the mesophyll, spongy layer of the leaf. The xylem supplies water for photosynthesis and the phloem transports prepared food to other parts of the body from the leaves.

Detailed explanation-3: -This vascular bundle works as two-way traffic as it allows the movement of substances upwards and downwards. Hence, Veins of leaves have both xylem and phloem.

Detailed explanation-4: -Answer and Explanation: Yes, the veins found in plants are composed of vascular tissues, containing xylem or phloem, and working to move water and nutrients throughout the plant’s various components, including its stem, branches, and leaves.

Detailed explanation-5: -Explanation: Phloem is located in the bark of trees and transports sugars (such as sucrose) and organic compounds to the rest of the plant from the leaves. The other plant vascular tissue is xylem. Xylem is located outer wood of trees, and transports water from the roots to the leaves of trees.
