The bamboos Listeni/bæmˈbuː/ are evergreen perennial flowering plants in the subfamily Bambusoideae of the grass family Poaceae. In bamboo, as in other grasses, 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. The dicotyledonous woody xylem is also absent. The absence of secondary growth wood causes the stems of monocots, including the palms and large bamboos, to be columnar rather than tapering.
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). Giant bamboos are the largest members of the grass family. 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 can be used in Culinary,Construction，Textiles，writing，weapons etc.
Bamboo has traditionally been used to make a wide range of everyday utensils, particularly in Japan, where archaeological excavations have uncovered bamboo baskets dating to the Late Jomon period (2000–1000 BC).

Bamboo has a long history of use in Asian furniture. Chinese bamboo furniture is a distinct style based on a millennia-long tradition.
Several manufacturers offer bamboo bicycles, surfboards, snowboards, and skateboards.
Due to its flexibility, bamboo is also used to make fishing rods. The split cane rod is especially prized for fly fishing. Bamboo has been traditionally used in Malaysia as a firecracker called a meriam buluh or bamboo cannon. Four-foot-long sections of bamboo are cut, and a mixture of water and calcium carbide are introduced. The resulting acetylene gas is ignited with a stick, producing a loud bang. Bamboo can be used in water desalination. A bamboo filter is used to remove the salt from seawater[dubious – discuss].
Food is cooked in East Timor in bamboo in fire. This is called tukir.
Many minority groups in remote areas that have water access in Asia use bamboo that is 3–5 years old to make rafts. They use 8 to 12 poles, 6–7 m (20 to 24 ft) long, laid together side by side to a width of about 1 m (3.3 ft). Once the poles are lined up together, they cut a hole crosswise through the poles at each end and use a small bamboo pole pushed through that hole like a screw to hold all the long bamboo poles together. Floating houses use whole bamboo stalks tied together in a big bunch to support the house floating in the water. Bamboo is also used to make eating utensils such as chopsticks, trays, and tea scoops.
The Song Dynasty (960–1279 AD) Chinese scientist and polymath Shen Kuo (1031–1095) used the evidence of underground petrified bamboo found in the dry northern climate of Yan’an, Shanbei region, Shaanxi province to support his geological theory of gradual climate change.
Bamboo processing tasks
Bamboo processing machines are usually built to perform a single task such as:
Splitting – separating the material in the direction of the fibers at right angles to the surface (radially)
Slicing – separating the material in the direction of the fibers parallel to the surface (tangentially)
Knot removing – cutting or grinding down the inter-segmental nodes.
Planing – smoothing the top, bottom and/or side surfaces of a split length
Cross cutting – cutting a length of stem into shorter sections
