Morphology

thallose = thallus (transparent) = thallus + ose

Formed by the noun 'thallus' plus the adjectival suffix '-ose', yielding the straightforward meaning 'having a thallus', though the base is a specialized botanical term.

Etymology

Thallose comes from the Greek thallos, meaning 'young shoot', and is related to thallus, the name for a flat plant body. So, a thallose plant is like a flat green 'shoot' spread out instead of having separate stems and leaves.
