Was given this plant but not 100% sure what it is?

One of my boyfriend’s clients gave him these cuttings and said it is a jade plant. So obviously, I assume it is jade and have been treating it as so! However, I got some speculation from others on whether or not it is actually jade due to the stem lacking nodes. Does anyone know if this is jade or not? I want to research how to keep it alive and have no idea what I’m looking for lol
