(ii) Features of sclerenchyma fibers:
● These are dead elements.
● They have thick wall of lignin, are elongated and pointed at ends.
● They have pits also.
● They mostly occur in groups.
Features of sclereids-
● These are dead elements.
● These are oval, spherical and are thickened due to lognin deposition.
● They have very narrow cavities at the centre.
