Which type of plant cell is involved in the tough fibers found in jute?

The correct response focuses on sclerenchyma cells, which play a key role in providing structural support to plants. Sclerenchyma cells are characterized by their thick, lignified cell walls, making them highly durable and effective in forming tough fibers. In the case of jute, it is the sclerenchyma fibers that give the plant its strength and toughness, which are essential for the production of jute fabric and other materials.

The other types of plant cells do not contribute to the tough, fibrous texture found in jute. Parenchymal cells typically serve as sites for storage, photosynthesis, and tissue repair, while collenchyma cells primarily provide flexibility and support to young stems and leaves but are not as strong or rigid as sclerenchyma. Meristematic cells are involved in growth and division, not in forming the structural fibers necessary for the toughness associated with jute. Thus, sclerenchyma is clearly the type of plant cell responsible for the characteristic strength and durability of jute fibers.
