Vascular tissue in stem, root and leaf consists of?
A
phloem
B
xylem
C
phloem and xylem
D
companion cell
Explanation: 

Detailed explanation-1: -Vascular tissue is comprised of the xylem and the phloem, the main transport systems of plants. They typically occur together in vascular bundles in all plant organs, traversing roots, stems, and leaves. Xylem is responsible for the transport of water and dissolved ions from the roots upwards through the plant.

Detailed explanation-2: -The vascular tissue of the stem consists of the complex tissues xylem and phloem which carry water and nutrients up and down the length of the stem and are arranged in distinct strands called vascular bundles.

Detailed explanation-3: -Xylem vessels transport water and dissolved mineral ions from the roots to the rest of the plant and also provide structural support. Phloem vessels transport dissolved substances, such as sucrose and amino acids, from the leaves to the rest of the plant.

Detailed explanation-4: -In leaves, the vascular bundles are located among the spongy mesophyll. The xylem is oriented toward the adaxial surface of the leaf (usually the upper side), and phloem is oriented toward the abaxial surface of the leaf.
