Does fern have a stem?

.
Do ferns need sun?
Ferns Need
Plenty of Indirect Light
Most ferns prefer indirect light, which means you should avoid placing them where sunlight will hit them—their leaves can get scorched if you do, resulting in a dry, crispy plant. Usually, the amount of light they would get near a north- or east-facing window is perfect.
Where do ferns grow best?

high or dappled shade
