HORTICULTURE

Detailed explanation-1: -The cambium cells on the inside become the xylem, a system of tiny tubelike cells that carry the tree’s water supply. These xylem layers give us the annual rings.

Detailed explanation-2: -A ring of secondary xylem or wood formed by the association of spring or early wood and autumn or late wood is called annual ring or growth ring. So, the correct option is ‘Growth ring’.

Detailed explanation-3: -These rings can tell us how old the tree is, and what the weather was like during each year of the tree’s life. The light-colored rings represent wood that grew in the spring and early summer, while the dark rings represent wood that grew in the late summer and fall.

Detailed explanation-4: -Locate the center of a tree stump or cross-section of a tree that has been cut. Look for alternating dark-colored rings and light-colored rings in the trunk. Count the dark rings to calculate the age of the tree. Look for wide, evenly-spaced rings that represent years of good weather. More items •12-Apr-2021
