Define and explain sclerenchyma tissues.
Sclerenchyma Tissues in plants are supporting tissues composed of various kinds of hard woody cells.
Mature sclerenchyma cells are usually dead cells that have heavily thickened secondary walls containing lignin and has a high cellulose content (60%–80%).
Sclerenchyma cells occur in many different shapes and sizes, but two main types occur: fibres and sclereids.
The tissues are dead which makes the plant hard and stiff (eg. Husk of coconut).
Structurally sclerenchyma cells are long and narrow and serves the function of providing structural support in plants.
