If tissues beneath the bark are severely damaged, transport of food throughout the plant would be hampered. Phloem damage prevents movement of sugars from leaves to roots and storage tissues, affecting growth, repair and survival of the tree.

The answers assume that debarking damaged bark and phloem significantly but xylem remained functional. If assumptions change, such as deeper xylem damage or partial bark removal, water transport, survival and overall effects on the tree would differ.
Collenchyma tissue provides flexibility to the young mango stem, allowing it to bend without breaking. If replaced by sclerenchyma, the stem would become hard and rigid, reducing flexibility and increasing chances of breaking during strong monsoon winds.
Coconut husk fibres contain sclerenchyma with thick lignified walls, making them hard and brittle. Coriander leaf stalks contain collenchyma with unevenly thickened walls and pectin, providing softness, flexibility and support without breaking during bending or movement.
Supporting tissues keep plants upright. Collenchyma provides flexibility, allowing fresh twigs to bend without breaking. Sclerenchyma makes seed coats hard and strong. Specialised parenchyma with air spaces helps aquatic plants float easily on water surfaces.
