If a plant is unable to transport food from leaves to roots, which tissue is malfunctioning?
(i) Xylem (ii) Phloem (iii) Epidermis (iv) Sclerenchyma
View Answer Hide Answer

The correct option is (ii) Phloem.

Phloem carries food from the leaves to the rest of the plant. If food cannot reach the roots, the phloem is not working. Xylem carries water, not food.
