When a tree is cut down, children love to run and then count the rings on the stump to see how old the tree Redding was. The general rule of thumb is that one single ring stands for one year, or one season of growth. A surprisingly true old tale, these rings would be the result of cell division within the cambium layer of the woody stem.
Kinds of Stems
There are two standard kinds of stems: herbaceous and woody. Herbaceous stems are located on most blooms, weeds and most green plants. Woody stems are located on many bushes and trees. There are a few differences between the two kinds of stems, however, the most obvious is that woody stems are composed mainly of a hardened cork rather than soft epidermis. The cork creates bark and hard woods as it ages.
Pith, Xylem, Cambium, Phloem, Bark…
In the inside out, a woody bark contains pith, xylem, cambium, phloem and bark. The pith, located in the center, can be made of wood fibers or can be hollow on a few plants. Xylem is the tough wood section that attracts water and minerals from the roots upward and serves as the support structure for your Stump Removal. Cambium is a dividing tissue, always forming xylem on the inside and phloem on the outside. Phloem is a sticky layer that disperses sugars throughout the tree Chico. Girdling to this layer cuts off supply to this tree and can cause slow starvation. The bark covers the entire stem as a sort of protection.
Put a Ring on Dicot
Stems can either be monocots and dicots. Monocots have packages of xylem and phloem mixed throughout their stem with vascular cambium between, a arrangement found on many herbaceous plants. Dicots, such as trees and lots of woody stems, organize their components in rings. A cork cambium, the growth layer, lies between the xylem and phloem from the ring. A tree having a ringed facility would therefore be classified as a woody dicot.
Growing Up
There are two ways a woody plant may develop. Principal growth adds height and length to the plant, creating small new branches. Secondary growth produces new thicknesses over previous year’s growth, thickening the divisions. The cork cambium divides its cells, half of them turning to xylem on the inside. Both sides expand over time and the phloem layer rises to the outside of the cambium. This procedure continues with one cycle every single full growing year, adding a ring per year.
