Think: 'GO' (the algae goes into the lichen) + 'NID' (like 'nest' – it nests within the fungus) + 'IUM' (a scientific ending) = the algal cell nested in a lichen.

Conceptual Metaphor

The gonidium is the photosynthetic 'engine room' or 'food factory' within the lichen 'apartment' built by the fungus.
