Question

Some points on sclerencyma cells

Answer 1

Answer:

Sclerenchyma, in plants, support tissue composed of any of various kinds of hard woody cells. Mature sclerenchyma cells are usually dead cells that have heavily thickened secondary walls containing lignin. The cells are rigid and nonstretchable and are usually found in nongrowing regions of plant bodies, such as the bark or mature stems. Sclerenchyma is one of the three types of ground, or fundamental, tissue in plants; the other two types are parenchyma (living thin-walled tissue) and collenchyma (living support tissue with irregular walls). Sclerenchyma cells occur in many different shapes and sizes, but two main types occur: fibres and sclereids.

Answer 2

1)The cells of this tissue are dead . They are long and narrow as the walls are thickened with suberin.

2)The walls of cells are so thick that there is no internal space inside the cell and between the cells.

3)It provides strength to the plants parts.
