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 tissue responsible for the flexibility of a young mango sapling's stem is collenchyma. Collenchyma is a living supporting tissue present in young stems and other young growing parts of plants. Its cells have unevenly thickened corners due to the deposition of pectin and cellulose, which provides both strength and flexibility. Therefore, the stem can bend during strong monsoon winds without breaking and recover its shape to some extent. If collenchyma were replaced by sclerenchyma, the stem would lose much of its flexibility because sclerenchyma cells have thick, lignified cell walls that make them hard and rigid. As a result, the stem would become stiff and would not bend easily under wind pressure. Strong winds could cause the stem to crack or break instead of bending. Thus, collenchyma provides the necessary balance of support and flexibility, which is essential for young plant parts.
