Why isn't movement considered a characteristic of all life?

Technically, all living things move in some way.

Different animals, like humans, dogs, and goats, can walk and run. Marine animals can swim and dive. Birds and some insects can fly around.

Plants can move, just not the same way animals can. For example, a sunflower will turn to face towards the sun. Although, plants don't have the ability to move from one place to another, or locomotion.

So, movement can be considered a characteristic of life, but locomotion is not. Plants and other living organisms cannot get up and move from one spot to another spot.
