(i) Identify the tissues shown in the figure.

(ii) Give the characteristic features of their cells.

(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-
