Temperate region

Vedclass · Answer

(D) . Annual rings are formed due to the variation in the climatic conditions of a region. In temperate regions,there is a clear distinction between the spring season and the autumn season. During spring,the cambium is very active and produces a large number of xylem elements with wider vessels (spring wood),whereas in autumn,the cambium is less active and produces fewer xylem elements with narrow vessels (autumn wood). This seasonal variation results in the formation of distinct annual rings.
