I would say pretty much everything. If it's living it obviously has to go through some kind of change.
Adaptation
Differentiation occurs several times during the development of a multicellular organism. The organism changes from a simple zygote to a complex system of tissues and cell types.
yeast
Mutations can improve the trait, harm the trait, or neither.
Metamorphis
Development
The changes that an organism undergoes during its lifetime can be called the growth and development of the organism.
developmental anatomy
Generally, the organism would be called sessile.

yeast
Stellar evolution is the term for the changes a star undergoes during its lifetime.
Mutations can improve the trait, harm the trait, or neither.
At first, because it could not be shown that changes to the organism acquired during its life were inherited by its offspring. Later, when we learned more about genetics, and ultimately DNA, this rejection was confirmed. Note though that since a few decades, we know of mechanisms that *do* allow certain changes at the molecular level acquired during the organism's lifetime to be inherited by offspring. This field of study is called: epigenetics.
development
Lamarck give the idea that an organism can pass on characteristics that it acquired during its lifetime to its offspring. Also known as heritability.
