Bamboo is any of a number of thousands of species and hundreds of genera belonging to the tribe Bambuseae. In this tribe, the two main genera are Bambusa and Phyllostachys, they both are vascular plants, seed plants, flowering plants and in the grass family. [1] Bamboos are monocots and angiosperms, which means they are flowering plants that bare seeds and produce fruits. They are the huge grass stem that spread out of whole world, and usually habitat in the tropical area or warm and cool temperature area. The average height of bamboo is about 45 feet, however, the tallest bamboo is over hundred feet which is giant bamboo (Dendrocalamus) and the smallest bamboo is dwarf bamboo which is about 4 inches tall. In these days, people use bamboo as landscaping such as gardening, fence, and such. Also, they are strong and hard so people are using bamboo as a scaffolding for buildings. [2]

Anatomy

This piture shows the size of the giant bamboo.

Bamboo is a monocotyledonae and a huge grass plant, which is a species of the tribe bambuseae. Bamboos are angiosperms meaning that they are flowering plants that bear seeds with a protecting layer, they also produce fruits, and have a water vascular system. It is monocot stem because it has a dispersed vascular bundle, they contain the xylem and phloem, which transport water and nutrients, single cotyledon, and have fibrous roots. Their roots are fibrous and start to grow at the rhizome and it also helpful to prevent the erosion. Moreover, the bamboo's flower influenced by their growing conditions, could die or they cannot flower. Also, they do not show both the secondary xylem and phloem, because they do not hold a vascular cambium which makes the vascular tissue and makes the stem thicker. (Miller and Levine p551-593) Moreover, the ability or power to make bamboo to grow, is all from the rhizome, also known as a root like stem or underground stem. Bamboo are different in their height, it depends on the species or the condition of the land and climate, and the range of bamboo's average height is about 25 to 65 feet. Some species or stems can grow about two feet in one day; and it grows faster than any other woody plants or growing plants. In addition, bamboo can grow to their maximum or limited height in a short time, which is about two months.[3] Now, the tallest bamboo is about 30 meters high, however, the smallest bamboo is about 4 inches high.

Reproduction

Bamboo flowering

There are two stages of the reproductive cycle of bamboo, reproductive and vegetative. The reproduction of angiosperms happens in the pollination of flowers and bamboo can reproduced by both wind and animal, which means the pollen may move from one tree to another by the wind or an animals. Most of the angiosperm plants have bright color however, most bamboo do not have bright color so it cannot really attract insects or any other animals to reproduce. Therefore, they are wind pollinated flowers and even the flowers are small but their pollen quantity is extensively a lot.(Miller and Levine p609-616) Vegetative breeding means cut up the rhizomes to split the thicket and rhizomes. About their growth rate, there are two types of bamboo's growth rate or speed, dendrocalamus and bambusa are usually clustered growth, which is slow in their growth rate, and phyllostachys and sinobambusa are usually divided growth, which is quick in their growth rate. [4] Also, it has two different kinds of growth by rhizome that are running and clumping bamboo. First, the clumping bamboos has short and slow of their spreading rate of rhizomes, and the running bamboo has long and fast of their spreading rate of rhizomes. Both clumping and running bamboo use their underground stem to spread their species to make new stems by break down the ground. By this fact, the growth rate is connected with the land conditions and climate. [5]

Ecology

This map shows distribution of Japanese timber bamboo in the North America.

Bamboo's ecology can be discussed based on two different types (clustered growth bamboo and divided growth bamboo). The clustered growth bamboos are usually can habitat in the tropical area where the weather is about 30 degrees celsius with soil that covered with yellowish brown sand. However, the divided growth bamboo can habitat in the area where the temperature is as warm as 20 degrees celsius in soil, which have some small stomes and enough deepness for the plant. In many countries in Asia grow bamboo in their personal ground at home even in the US they grow bamboos in their personal ground. Bamboos usually grows in the area where the pandas are dwelling.[6] For example, phyllostachys are distributed in states of California, Florida, Kentucky, Louisiana, North Carolina, South Carolina, Texas and also, Bambusa are distributed in state of Florida.

Uses

In these days, people uses bamboo for building supplies, foods, or to decorate on something. First, people in Southern Asia eat tender bamboo as their meal they eat the bamboo's shoot or stems. Therefore, bamboo can be a source of food for human, moreover, bamboo is also a source of food, especially for giant panda. Bamboo is well nutritional food and bamboos are good food for diet, giant pandas eat of bamboo about 4.5 tons in each year. [8] Second, bamboo can decorate the design of the house more stylish. Bamboo can be uses as a fences, because their heights are usually high and they are strong and hard. In addition, people can decorate their garden with bamboo, in many Asian countries, people owns the garden with a lot of bamboo, because Asian people believe that bamboo brings peace and fortune to them.
