Morphology
radical = radic + al
The botanical sense literally relates to 'root' (i.e., arising from the root), but this relation relies on technical/botanical knowledge and the combining form is not a standalone English word.
Etymology
Radical comes from the Latin radix, meaning 'root'. In plants, radical parts grow at or from the 'root', which is why the word describes leaves or shoots at the base.
