Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the function of vascular tissue?
A
physical support of the plant
B
transport water and nutrients
C
defend against predators
D
None of the above
Explanation: 

Detailed explanation-1: -The vascular tissues of plants, which are composed of specialized conducting tissues, xylem and phloem, form continuous systems through the plant body and provide transport pathways for water, nutrients, and signaling molecules and support a plant body against mechanical stresses.

Detailed explanation-2: -Xylem is the tissue responsible for supporting the plant as well as for the storage and long-distance transport of water and nutrients, including the transfer of water-soluble growth factors from the organs of synthesis to the target organs.

Detailed explanation-3: -Vascular tissue transports water, minerals, and sugars to different parts of the plant. Vascular tissue is made of two specialized conducting tissues: xylem and phloem. Xylem tissue transports water and nutrients from the roots to different parts of the plant, and also plays a role in structural support in the stem.

Detailed explanation-4: -Water Movement in Vascular Plants The xylem is comprised of dead cells and is responsible for the transportation of water from the roots to the rest of the plant. By contrast, the phloem carries nutrients from the leaves to the roots and other parts of the plant in a process known as translocation.
