Wood is what keeps trees and shrubs upright, and what transports h2o through the roots towards the leaves. The two most important chemical substances in wood are cellulose and lignin.
Wood can be dated by carbon courting and in a few species by dendrochronology to ascertain each time a wooden object was established.
Idealised nephrozoan entire body system.[c] Having an elongated body and also a way of motion the animal has head and tail finishes. Perception organs and mouth sort The idea of the head. Opposed round and longitudinal muscles permit peristaltic motion.
