Q. Which of the following is/are true for sclerenchyma?

1. It is a permanent tissue.
2. It is made of sclerenchymatous tissue.
3. The cells of this tissue are living.

Select the correct answer from the codes given below:
Answer: Only 1 and 2
Notes: One type of permanent tissue is sclerenchyma. It is the tissue which makes the plant hard and stiff. We have seen the husk of a coconut. It is made of sclerenchymatous tissue. The cells of this tissue are dead. They are long and narrow as the walls are thickened due to lignin. Often these walls are so thick that there is no internal space inside the cell.
