Question

Whese parts of these plant have fibre

Answer 1

Answer:

Plant fibers are found as structural elements in all higher plants. Botanically the fiber is considered to be an individual cell, which is part of sclerenchyma tissue and is characterized by a thick cell wall and a high length-to-diameter ratio (reaching 1000 and more). The basic function of sclerenchyma is providing mechanical integrity to the plant. Spindle-shaped cells with tapered ends are considered to be a characteristic feature of the fiber cell. According to this definition, cotton (Gossypium spp.) fiber – probably the most well-known plant fiber – is not a fiber, but a trichome, the extrusion of epidermal tissue.
