    If an old tree is cut transversely, distinct growth rings are visible and it is possible to calculate the age of a tree by counting such rings. These rings are most prominent in:

    A)  Tropical plants

    B)         polar plants

    C)  Sub-tropical plants

    D)  temperate plants

    Correct Answer: D

    Solution :

    [d] The rings are more visible in temperate zones, where the seasons differ more markedly. Many trees in temperate zones make one growth ring each year, with the newest adjacent to the bark. Hence, for the entire period of a tree's life, a year-by-year record or ring pattern is formed that reflects the age of the tree and the climatic conditions in which the tree grew.
