Understand the concept of indeterminate cleavage: In early embryonic development, cleavage refers to the series of cell divisions that occur immediately after fertilization. Indeterminate cleavage is a type of cleavage where each cell produced by early divisions retains the potential to develop into a complete organism.
Recognize the significance of indeterminate cleavage: This type of cleavage is characteristic of deuterostomes, such as humans and other vertebrates, where the fate of the cells is not determined early on. This means that if the cells are separated, each has the potential to develop into a complete embryo.
Differentiate between indeterminate and determinate cleavage: In determinate cleavage, the fate of each embryonic cell is set early in development, meaning that separated cells cannot develop into a complete organism. This is typical of protostomes, like many invertebrates.
Apply this understanding to the problem: The question asks about the outcome of indeterminate cleavage. Given the characteristics of indeterminate cleavage, the embryonic cells retain the capacity to develop into a complete embryo.
Conclude with the correct choice: Based on the understanding of indeterminate cleavage, the correct answer is that these cells 'retain the capacity to develop into a complete embryo.'
