Final answer:
In oogenesis, the smaller cells formed that carry minimal cytoplasm and organelles are called polar bodies; these typically degenerate while the larger cell can become an ovum upon fertilization.
Step-by-step explanation:
During the process of oogenesis, a diploid cell known as a primary oocyte undergoes the first division of meiosis to form two cells: a large cell with most of the cytoplasm and cellular organelles called a secondary oocyte, and a smaller cell with minimal cytoplasm and organelles. This smaller cell is referred to as a polar body, which generally degenerates and breaks down. If the secondary oocyte is fertilized by a sperm, it proceeds to the second meiotic division, producing an ovum along with another polar body. The ovum is a large haploid gamete ready for fertilization, carrying all the necessary resources to support the early development of the zygote.
