Which of the following tissues has dead cells?

Options

A. Parenchyma
B. Sclerenchyma
C. Collenchyma
D. Epithelial tissue

Answer

B

Explanation

Sclerenchyma cells are the permanent tissues present in the plants. They provide hardness and stiffness to the plant and are composed of dead cells. This tissue is present in stems around vascular bundles in the veins of leaves and in hard covering of seeds and nuts.
e.g, the husk of coconut is made up of sclerenchymatous tissues. The cells of
sclerenchyma are long narrow and thickened due to lignin.
