Meaning of protocorm | Babel Free

Definitions

A tuberous mass of cells that is the embryonic form of orchids and club mosses

Examples

“Orchids rely on fungi to reproduce. Their tiny seeds don't have any on-board nutrients (like beans and apples) and will not germinate until they are infected by a symbiotic fungus which supplies them with food. Known as a protocorm, this tiny orchid-fungus ball grows, turns green and eventually starts to photosynthesise.”
