TRANSPORT IN PLANTS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Vascular system that transports water and minerals from roots to the leaves in upward direction is known as ____
A
Mid rib
B
Phloem
C
Stomata
D
Xylem
Explanation: 

Detailed explanation-1: -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. Xylem cells constitute the major part of a mature woody stem or root.

Detailed explanation-2: -Xylem tissue transports water and nutrients from the roots to different parts of the plant, and includes vessel elements and tracheids, both of which are tubular, elongated cells that conduct water.

Detailed explanation-3: -Complete answer: The upward movement of water from root to leaves in a plant is known as Ascent of sap. It is carried out by xylem tissues that take water and minerals from the roots to the crown.

Detailed explanation-4: -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-5: -Abstract. 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.
