Morphology

tubule = tube (transparent) = tube + ule

The word is a diminutive formation from 'tube' with the suffix '-ule' indicating a small tube, so the meaning is directly inferable from the base.

Etymology

Tubule comes from the simple word tube plus the ending -ule, which means 'small'. So a tubule is literally a 'small tube', a helpful image for remembering its modern meaning as a very thin tube in plants or animals.
