What carries food from the roots to all plant parts?
A
phloem
B
xylem
C
root hairs
D
stomata
Explanation: 

Detailed explanation-1: -The vascular system is comprised of two main types of tissue: the xylem and the phloem . The xylem distributes water and dissolved minerals upward through the plant, from the roots to the leaves. The phloem carries food downward from the leaves to the roots.

Detailed explanation-2: -Stems possess specialized tissues called vascular bundles that conduct food and water to all parts of the plant. Xylem and phloem are conducting tissues that together form the vascular bundles. Phloem carries food from the leaf to the different parts of the plant.

Detailed explanation-3: -xylem, plant vascular tissue that conveys water and dissolved minerals from the roots to the rest of the plant and also provides physical support.

Detailed explanation-4: -Xylem transports and stores water and water-soluble nutrients in vascular plants. Phloem is responsible for transporting sugars, proteins, and other organic molecules in plants.

Detailed explanation-5: -Xylem is the specialised tissue of vascular plants that transports water and nutrients from the plant–soil interface to stems and leaves, and provides mechanical support and storage. The water-conducting function of xylem is one of the major distinguishing features of vascular plants.
