Question

Age cannot be determined by counting rings in the trees of
A. Temperate deciduous forest
B. Temperate evergreen forest
C. Tropical deciduous forest
D. Tropical evergreen forest.

Answer 1

Hint:- One can know the age of a tree by counting the rings on the tree trunk. The rings that are formed on the tree trunks are called the annual rings. As a tree grows it forms a new wood outside. To the outer part of the trunk. If we take the section of the tree then the oldest part of the tree is seen as a smaller ring, and the younger part of the tree is seen as a larger ring.

Complete step-by-step solution:-
The rings of trees are also called the growth rings. There are two types of rings- a light ring and a dark ring. When the tree grows quicker it adds light rings. This is during spring and early summer. Dark rings are added during its slow growth. These rings are formed as a result of the vascular tissue. Just beneath the bark, there is the presence of a tissue called cambium.
During the spring season, this cambium divides, and the vessels formed are larger and denser. They form the earlywood or light rings. During summer, the cambium produces smaller, thicker cells. They form the dark rings. The characteristics of different types of forests are discussed below:

Note:- The study of tree anatomy is termed as dendrology. Counting the growth ring is one of the ways to know the age of a tree. There are other ways available to know the age of the tree they include:
1. Measuring the circumstances of the trunk.
2. Counting the branches in a row.
