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.

Collenchyma — flexible, thick corners

Sclerenchyma — hard, thick walls

View Answer Hide Answer

The flexibility is given by collenchyma , whose living cells have thick, pectin-rich corners that bend without breaking.

If collenchyma were replaced by sclerenchyma, the stem would become hard and stiff. In strong winds it could not bend, so it would be brittle and might snap instead of swaying.

Why the Sapling Bends
Collenchyma
Living cells with pectin-rich corners bend without breaking.
↓
If replaced by sclerenchyma
Lignified cells make the stem hard and stiff.
↓
A stiff stem could snap in strong winds
