What group of plants common during the Triassic period had seeds lacking a protective outer coat?
The group of plants common during the Triassic period that had seeds lacking a protective outer coat is known as gymnosperms, specifically the early forms of seed plants like cycads and ginkgoes.

How does ease of splitting open a monocotyledon seed compare with that of splitting open a dicotyledon seed?
Monocotyledon seeds are generally more difficult to split open compared to dicotyledon seeds because they have a tougher outer seed coat. Dicotyledon seeds typically have a softer seed coat that is easier to split open to access the two cotyledons inside.
