Yes, it is true that Plant fiber is a collenchyma cell.
Collenchyma tissue is a tissue which is flexible. It gives plant flexibility and support. That's just what a Plant fiber does. It gives flexibility and support to the plant. So, it is not wrong to call the plant fiber a collenchyma cell.
true because all plant have cell collenchyma cell
The statement is False; plant fiber is not a collenchyma cell but rather comes from sclerenchyma cells. Collenchyma cells are living and flexible, while sclerenchyma cells are dead at maturity and provide rigidity. Therefore, plant fibers are associated with the sclerenchyma type of tissue, not collenchyma.
