Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In vascular plants, ____ transports water, while ____ transports sugars (food).
A
Phloem; Xylem
B
Xylem; Phloem
C
Roots; Stem
D
Stem; Roots
Explanation: 

Detailed explanation-1: -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-2: -Sugars produced in sources, such as leaves, need to be delivered to growing parts of the plant via the phloem in a process called translocation, or movement of sugar.

Detailed explanation-3: -Water and sugars are transported by xylem vessels and phloem tubes, respectively. Since these two conduits are hydraulically connected, it can be expected that both transport processes are physiologically coupled.

Detailed explanation-4: -Phloem is a highly specialised vascular tissue that forms an interconnected network of continuous strands throughout a plant’s body. It transports sugars, nutrients, and a range of signalling molecules between leaves, roots, flowers, and fruits. As a result, phloem is central to plant function.

Detailed explanation-5: -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.
