MP Board · Class 9 · Science · TissuesWhat is the main function of sclerenchyma tissue in plants? Mention two examples where it is found.
Step-by-Step Solution
Sclerenchyma tissue provides structural strength, rigidity, and hardness to plant parts. Its cells are dead, long, narrow, and have thick walls depositioned with lignin, leaving no internal space. It makes the plant parts hard and stiff to withstand environmental stress. Examples of sclerenchyma tissue include coconut husk (coir) and the hard coverings of seeds and nuts.
