Summary Introduction

To write:

How the age of a tree estimated and approximate age of given tree.

Introduction:

The most accurate manner to estimate tree age is to count the annual rings of wood growth. Tree rings shape due to the fact at some point of each growth season new water and food conducting cells (tracheids) are transferred across the perimeter of the tree trunk. Cells with inside the spring growth generally tend to be large with thinner walls than the preceding set of cells produced on the give up of the preceding summer. Annual rings may be counted the use of two different methods. We can extract an increment center from the tree the use of an increment borer.

Explanation of Solution

The age of a tree may be estimated via way of means of counting the annual growth rings atthe bottom of its trunk. The light-colored rings are the wood that grew in spring and early summer time season,at the same time as the dark rings indicate increase in overdue summer time season and fall. So, a light ring and dark ring together represent one yearof increase. A sapling (young tree) grows a whole lot quicker than an adult tree. The approximate age of the given tree is 15-16years.

Conclusion

So, the age of a tree can be determined by counting the yearly growth rings at the bottom of its trunk.
