Document Summary
Fibres that are used for sale cloth, for ropes, and fishing line. Also used to make a type of paper (hemp)- 2000 years ago. Fibres are found in just about any plant organ. Fibre is a chain of long thin cells that are thread-like with thick lignified walls. Individual plant fibre under a microscope- it is hollow in the middle, because you have the plant cell with all the features but you get a secondary cell wall that when it thickens it kills off all the organelles. Sclerids: are sclerenchyma cells that function in structural support in fruits (also known as stone cells. ) (found in unripe pear) Fibre cells are elongate; have tough cell walls. They can"t break easily (stem) because of the fibre strands in the stem. Each bundle (the outside) has hollow fibre cells that protect the phloem cells that have thin cell walls from being damaged. Cotton has thin fibre while burlap has thick fibre.
