you count the rings in the trunk, each ring is one year starting from center working out. as far as i know you cannot tell by roots or bark.

There are two ways to get the age of a tree. 1. Cut the tree down and count the darkest growth rings (late wood) from the stump. 2. Using a Increment Bore 4 1/2 feet (Breast Height) from the ground, bore into the tree as centerly as possible and count the dark rings from the core to the inner bark. You will also need to know the species of the tree to find a table to add typical years for that individual tree to reach 4 1/2 feet. Usually 5-7 years typically. However, sometime trees will produce a false growth ring when an unusual climate change occurs. The false growth rings are usually easy to identify because they look odd when compaired to the surrounding rings, they are typicallly closer to another ring compaired to the others and thinner. If the tree is under competition with other trees and/or getting older growth will slow cause the rings to get closer typically closer to the bark. The lighter rings are summer wood.
You can not determine age from bark or roots. Bark measurements are used to measure thickness to figure out wood diameter.

Forester7 has it right,
But do not look at the bark. The cambium is the secondary meristem which creates tree girth. The wood as we know it is xylem tissue, while the bark is phloem. While equal layers of xylem and phloem are produced, the phloem (bark) sloughs off. Counting the bark is innacurate. If your question is taken directly from your homework, it sould be rephrased.
The science of counting tree rings is called Dendrochronology.

The only way I know is to count the growth rings of a cross sectional area of the main trunk. Of course you have to kill the tree to do this.

By checking in the barks. The amount of ANNUAL RINGS may give you their age.

I'm going to assume your a 4th grader or either really stupid Yes trees die of old age

you count the rings from the center, one ring denotes one year

Jokerswild is exactly right.
