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.
Aamrapali observed that a young mango sapling’s stem bends flexibly during monsoon winds and does not break. Which tissue is responsible for this flexibility? Predict and provide your explanation of the impact if the existing tissue was replaced by sclerenchyma.

The flexibility of the young mango sapling’s stem is due to collenchyma tissue, which has unevenly thickened walls containing pectin. This tissue provides support with flexibility, helping the stem bend during strong winds without damage. If sclerenchyma replaced collenchyma, the stem would become hard, rigid and brittle because sclerenchyma has thick lignified walls, making the sapling more likely to break.
