Question

Sclereids are the sclerenchyma cells with very thick secondary wall deposits and provide mechanical support. In which of the following plant organs one would expect to find abundant sclereids?

• A. Underground tuberous roots
• B. Leaves of floating hydrophyte
• C. Flower petals of mesophytes
• D. Petioles of xerophytic plant

Answer 1

The correct option is D Petioles of xerophytic plant

Petioles of a xerophytic plant have evolved to become phyllode which needs more mechanical support than the others and that is why one would expect to find abundant sclerites in it.

So, the correct option is D.
