Morphology

macroalga = alga (semi-transparent) = macro + alga

The meaning is directly compositional as 'macro-' meaning large plus 'alga', but the classical combining form may not be fully accessible to average learners.

Etymology

Macroalga combines the part macro- ('large') and alga ('seaweed'), like the common word algae. So it simply means 'large seaweed', which is why we use it for visible seaweeds such as kelp.
