Question

The tissue that provides strength and rigidity to the plant is ________.

Answer 1

Sclerenchyma:

1. The plant's sclerenchyma cell walls offer mechanical strength.
2. The presence of xylary fibers and conducting sclerenchyma, i.e. tracheary elements, adds mechanical stiffness to the part.
3. The cell walls of tissues such as sclerenchyma, xylem tracheid, and vessels are thickened significantly with lignin.
4. The cell wall provides strength due to secondary wall thickening.

Final Answer: The tissue that provides strength and rigidity to the plant is Sclerenchyma.
