The correct option is (ii) phloem. Phloem transports food prepared in leaves to roots and other plant parts. Malfunctioning phloem disrupts movement of sugars and nutrients, affecting growth, storage and normal metabolic activities in plants.
If a plant is unable to transport food from leaves to roots which tissue is malfunctioning? (i) Xylem (ii) Phloem (iii) Epidermis (iv) Sclerenchyma

The correct answer is (ii) phloem. Phloem tissue is responsible for transporting food materials, especially sugars produced during photosynthesis, from leaves to other plant parts including roots, stems and fruits. If phloem stops functioning properly, food distribution becomes disturbed, leading to poor growth, reduced storage and weakening of the plant’s metabolic and developmental processes.
