How do I identify an adjective?

•  Identify the noun and find the description.

Ex:

In Japan, some people grow miniature trees that have a famous history and an important place in horticultural art. Through pruning and fertilization, the trees are trained to keep the shape and proportion of larger trees. The trees often have small leaves and small fruit. The trees have an old and wind-swept appearance, as though they had grown in the outdoors.
