The bamboos are a subfamily of flowering perennial evergreen plants in the grass family Poaceae.
Giant bamboos are the largest members of the grass family. In bamboo, the internodal regions of the stem are usually hollow and the vascular bundles in the cross section are scattered throughout the stem instead of in a cylindrical arrangement.
Bamboos include some of the fastest-growing plants in the world，due to a unique rhizome-dependent system. Certain species of bamboo can grow 91 cm (3 ft) within a 24-hour period, at a rate of almost 4 cm (1.5 in) an hour (a growth around 1 mm every 90 seconds, or one inch every 40 minutes). Bamboos are of notable economic and cultural significance in South Asia, Southeast Asia and East Asia, being used for building materials, as a food source, and as a versatile raw product. Bamboo has a higher specific compressive strength than wood, brick, or concrete and a specific tensile strength that rivals steel. Bamboo is an eco-friendly material, so we make disposable cutlery like fork、spoon、knife、coffee stirrer etc. with bamboo instead of plastic, that will be help to reduce the use of fossil energy and environmental pollution.
