Solution
The correct option is C Count the number of annual rings at the base of main stem A tree ring is simply a layer of wood produced during one tree's growing season. Tree rings have many uses. Each tree ring marks a line between the dark late wood that grew at the end of the previous year and the relatively pale early wood that grew at the start of this year. One annual ring is composed of a ring of early wood and a ring of late wood. Growth rings, also referred to as tree rings or annual rings, can be seen in a horizontal cross section cut through the trunk of a tree.
Growth rings are the result of new growth in the vascular cambium, a layer of cells near the bark that is classified as a lateral meristem. This growth in diameter is known as secondary growth. Visible rings result from the change in growth speed through the seasons of the year.
