Gymnosperm Defining Trait: the Naked Seed
Captions available
The idea
A gymnosperm produces a "naked" seed, exposed on a modified leaf structure such as a cone scale, rather than enclosed inside an ovary.
In practice
A pine seed sits exposed on a woody cone scale's surface, with no surrounding fruit tissue covering it.
Where people slip
"Naked" describes the seed's lack of an enclosing ovary wall, not any lack of a protective coat around the embryo.
