Question

Fibre , the longest plant cell belongs to which tissue?

• A. Parenchyma
• B. Collenchyma
• C. Sclerenchyma
• D. Aerenchyma

Answer 1

The correct option is C Sclerenchyma

Sclerenchyma is a simple permanent tissue which is mainly composed of dead cells. The walls consist of cellulose, hemicellulose and lignin. These are the principal supporting cells in plant tissues that have ceased elongation.
Sclerenchyma fibres are of great economical importance, since they constitute the source material for many fabrics (flax, hemp, jute, ramie).

So, the correct answer is option C.
