Question

Which of the following transports

water from the roots of the plant to its

leaves?

A. Xylem

B. Phloem

C. Both xylem and phloem

D. Cortex​

Answer 1

Ans. A

Sol. Xylem/Sapwood

• The xylem, or sapwood, comprises the

youngest layers of wood. Its network of

thick - walled cells brings water and

nutrients up from the roots through tubes

to the leaves and other parts of the tree.

• Xylem cells in the central portion of the

tree become inactive and die as tree

grows. These led to the formation of

tree’s heartwood.

Phloem/Inner Bark

• The phloem or inner bark, which is

found between the cambium and the

outer bark, acts as a food supply line by

carrying sap (sugar and nutrients

dissolved in water) from the leaves to the

rest of the tree.
