Simplified etymology

Tuber entered English in the late 16th century from Latin tuber, meaning “hump” or “swelling.” Its plural, tubera, may also lie behind the word truffle.

Borrowed from Latin tuber, 'swelling, hump, or knob.' Botany applied the shape word to a swollen underground storage organ, while anatomy retained the older general sense of a rounded projection.
