How does a sieve tube differ from a companion cell?

Sieve tubes members do not have ribosomes or a nucleus and thus need companion cells to help them function as transport molecules. Companion cells provide Sieve tube members with proteins necessary for signaling and ATP in order to help them transfer molecules between different parts of the plant.
