Based on the provided cross-section diagrams of gastrulation, how many distinct fluid-filled compartments cavities are observable in a fully formed gastrula, considering both the original blastocoel and any newly formed cavities?
Explanation
The cross-section diagram of the gastrula clearly shows two main cavities: the primitive gut archenteron , which is a new formation, and the remaining space of the original blastocoel. Therefore, there are two distinct fluid-filled compartments.
