During the cap stage, which tissues comprise the tooth germ?

Explanation:
During the cap stage, the tooth germ is a three-tissue structure: the enamel organ, the dental papilla, and the dental sac. The enamel organ comes from oral epithelium and will form enamel. The dental papilla, derived from ectomesenchyme, will give rise to dentin and the pulp. The dental sac surrounds the germ and becomes the supporting tissues: cementum, the periodontal ligament, and part of the alveolar bone. Morphologically, the enamel organ sits like a cap over the dental papilla, all enclosed by the dental sac. This coordinated three-tissue arrangement is what defines the tooth germ at this stage.
