Understand the context: The problem is asking about a specific phase in early embryonic development where cells divide repeatedly without growing significantly.
Identify the process: This phase is known as 'cleavage,' which is characterized by rapid cell division following fertilization, leading to the formation of a blastula.
Differentiate from other processes: Meiosis is a type of cell division that reduces the chromosome number by half, binary fission is a form of asexual reproduction in prokaryotes, and fragmentation is a form of reproduction where an organism breaks into parts that develop into new individuals.
Recognize the outcome: Cleavage results in a multicellular structure called a blastula, which is a hollow sphere of cells.
Confirm the correct term: The correct term for the process described in the problem is 'cleavage,' as it matches the description of repeated cell divisions without significant growth.
