All Living Things Move, Even the Ones That Stay Put

Internal movement happens inside every living organism, even ones that never leave their spot.
It keeps cells alive by moving nutrients, wastes, and organelles to where they are needed.
Locomotion is movement of the whole organism from one place to another.
Only some organisms can do it, and it lets them find resources, escape threats, and reach mates.

Example

Internal movement in plants: water and minerals move through xylem and phloem.
Internal movement in animals: peristalsis and blood circulation shift materials around the body.
Internal movement in unicellular organisms: cytoplasmic streaming carries nutrients and organelles.
Locomotion in a cheetah: sprinting to catch prey.
Locomotion in bacteria: swimming using flagella.
