Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of these is true?
A
Xylem vessels carry water and dissolved minerals up the plant
B
Phloem tissue carry water and dissolved minerals up the plant
C
Xylem vessels carry dissolved sucrose up and down the plant
D
None of the above
Explanation: 

Detailed explanation-1: -Xylem transports water, minerals, and nutrients from the soil to all the plant parts. There are two types of “transport” tissues in plants-xylem and phloem. Water and solutes are transported by the xylem from the roots to the leaves, and food is transported from the leaves to the rest of the plant by the phloem.

Detailed explanation-2: -xylem, plant vascular tissue that conveys water and dissolved minerals from the roots to the rest of the plant and also provides physical support. Xylem tissue consists of a variety of specialized, water-conducting cells known as tracheary elements.

Detailed explanation-3: -Explanation: Xylem transports water and mineral salts from the roots up to other parts of the plant, while phloem transports sucrose and amino acids between the leaves and other parts of the plant.

Detailed explanation-4: -In plants, vascular tissue named xylem transports water and minerals from roots to shoots and leaves. Transportation of water takes place through tracheids and vessels, the dead cells of xylem.

Detailed explanation-5: -1. Xylem tracheids-These are dead tubes like hollow cells. They have thick lignified walls and functions in transport of water and minerals.
