There are principally two methods, that are used to measure the ratio of height to weight, namely, the common formula and the second one is BMI or Body Mass Index. The Common Formula A common notion that is supported by all physicians is that a person's ideal weight should be equivalent to: Height in cm (-) 100
The sections are defined by thin areas called nodes. The parts of the culm between these nodes are called internodal areas. The length of the internodal areas, and the thickness of their walls, will vary greatly, depending on the species of bamboo.amboo is a tall grass that can be used both as a lumber and as a food. Some forms of bamboo can reach 70 feet tall. Bamboo stalks, more properly called culms, are the main growth supports for the plant's leaves.
In the root, the xylem (stained green-blue in the photo) are arranged. in some sort of star or cross-shape. The phloem tissue are arranged in. smaller groups in between each spike of the xylem cross-shape. Around the bundle is a special layer of cells called the endodermis. This has. a key role in getting water to the xylem vessels. Inside the endodermis is a. layer of meristem cells called the pericycle. The vascular bundles are found near the outer edge in. the stem. The xylem is found towards the inside of. each vascular bundle (see the diagram), and the. phloem towards the outside. In between the xylem and the phloem vessels there is a layer of cambium. This is a layer of meristem cells which can divide to produce more phloem or xylem. The diagram to the right (top) shows a vascular bundle in close detail. The below diagram shows a transverse section of a stem, where you can see the entire outer ring
