Mitosis
D
Meiosis
Verified step by step guidance

Understand the context: The problem is asking about a process that involves rapid cell division of a zygote, which is the initial cell formed when a sperm cell fertilizes an egg cell.
Identify the key term: 'Cleavage' is the process that involves rapid cell division of the zygote. It is characterized by a series of mitotic divisions that occur without the zygote growing in size, leading to the formation of a multicellular structure called a blastula.
Differentiate between the terms: 'Cytokinesis' is the division of the cytoplasm during cell division, 'Mitosis' is the process of cell division that results in two identical daughter cells, and 'Meiosis' is a type of cell division that reduces the chromosome number by half, resulting in four genetically diverse daughter cells.
Focus on the process: Cleavage is unique because it involves rapid, successive mitotic divisions without growth, which is crucial for the early stages of embryonic development.
Conclude with the correct process: Given the options, 'Cleavage' is the process that specifically refers to the rapid cell division of the zygote, distinguishing it from the other processes listed.
