Study Notes
Developmental Characteristics
- Protostomes are characterized by Spiral cleavage, a type of development where the cells of the embryo divide in a spiral pattern.
- Deuterostomes, on the other hand, are associated with Radial cleavage, a type of development where the cells of the embryo divide in a radial pattern.
Cell Determination
- In protostomes, the fate of each cell in the adult organism has already been determined.
- In contrast, the cells of the eight-cell embryo in deuterostomes are totipotent, meaning each cell has the ability to give rise to any cell type in the adult organism.
This quiz covers the difference between protostome and deuterostome development, focusing on determinate and indeterminate development patterns. Test your understanding of how the fate of cells is determined in these two types of embryonic development.
