Bast fiber
* are also generally stiffer and stronger than cotton fibers.
* come from the phloem tissues of dicotyledonous plants.
* is natural fibre

Plant fiber
* Some plant fiber finds in wood.
* are composed of cellulose - long chain of glucose molecules, animal fibers are protein.

Plant fibre
* are strong because of the arrangement of cellulose in the cell wall
  - the basis of fabric such as cotton
+ Fibre
  * A 'fibre' or 'fiber'Fibre' is the preferred spelling in the United Kingdom and other Commonwealth countries. Plant fibres are the basis of fabric such as cotton. Silk and wool fibres come from animals. In the 20th century many artificial fibres were invented like nylon and polyester.

* carry information from the brain to the body and back to the brain
  - the signals to the brain, which interprets the nerve signals as sound
* conduct impulses faster when warmed and slower when cooled.
* connect the brain directly to both the fallopian tubes and the uterus
  - thymus, spleen, lymph nodes and bone marrow
* exit the spinal cord and connect to each organ throughout the body.
* have a high metabolic demand and little reserve of energy stores.
* help communicate impulses to and from the brain.
