Tree growth rings (and some other kinds like those of shells) are caused by the difference in growth during the different seasons: autumn and winter less growth, spring & summer more growth.
Most of a tree's trunk is not made of growth rings, but these rings are an important part of its structure. Growth rings, formed by annual layers of new wood, represent the tree's growth over time and can be seen when a trunk is cross-sectioned. The trunk itself is primarily composed of various types of wood, including sapwood and heartwood, which provide strength and support. The growth rings help indicate the tree's age and growth conditions but are just a part of the trunk's overall composition.

The rings in a woody stem, also known as growth rings or annual rings, are primarily made up of layers of xylem tissue. Each ring represents a year of growth, with the inner part typically consisting of older, darker wood and the outer part made up of lighter, newer wood. The thickness of the rings can vary based on environmental conditions, indicating the growth rate during that year. Additionally, the rings are composed of cellulose, lignin, and other organic compounds that contribute to the stem's strength and structure.
Annual growth rings are commonly studied in trees.

A clams growth rings can be, tan, gold, brown, even red.
Yes, growth rings have been found on fossilized fish scales. These rings, similar to tree rings, can provide information about the age and growth rate of the fish during its lifetime. Studying these growth rings can help researchers understand the fish's environment and lifecycle.
Palms do not show growth rings.
The rings on a clam show where the growth of one year ends. Basically you can count the rings to see how old the clam is just like a tree! Each ring shows the growth of that year.

the size of the rings would depend on the growth cycle of the tree. If the growth time for a certain year is longer, the ring will be wider, it the growth time of the year is shorter then the ring will be smaller.
Yes, branches do have growth rings. Each year, a tree adds a new layer of wood to its branches, which can be seen as rings when the branch is cut. These rings can provide information about the age and growth history of the tree.
