What are the functions of vascular bundles?
A
transport sugars
B
provide mechanical support for the plant
C
transport water and minerals
D
all of the above
Explanation: 

Detailed explanation-1: -The vascular bundle is known as conducting vessel of a plant. The vascular bundle consists of the xylem and phloem. They aid in water and dissolved mineral absorption, as well as their transmission to the stem and the storage of reserve foods. In the vascular bundle, phloem and xylem are separated by only a few cells.

Detailed explanation-2: -A vascular bundle is a part of the transport system in vascular plants. The transport itself happens in the stem, which exists in two forms: xylem and phloem. Both these tissues are present in a vascular bundle, which in addition will include supporting and protective tissues.

Detailed explanation-3: -The two primary vascular tissues are xylem, which transports water and dissolved minerals from the roots to the leaves, and phloem, which conducts food from the leaves to all parts of the plant.

Detailed explanation-4: -It is a component of the transport system in vascular plants. It comprises two tissues, i.e. phloem and xylem. Xylem comprises vessel elements, tracheids, xylem sclerenchyma, xylem parenchyma, and xylem fibers.

Detailed explanation-5: -Within the stem, bundles of vascular tissue, consisting of xylem and phloem, transport water, nutrients, food, and other chemicals between the different parts of the plant. The xylem transports water and dissolved minerals from the roots to the stem and leaves.
