Oogenesis and spermatogenesis are the processes of meiosis that occur in females and males, respectively, leading to the formation of gametes (eggs and sperm). There are several differences between these two processes.
First, oogenesis forms two polar bodies, while spermatogenesis only forms one. During oogenesis, the primary oocyte undergoes two rounds of meiosis, resulting in the formation of one mature egg and two polar bodies. The polar bodies do not have the potential to be fertilized and serve mainly to discard excess genetic material. In spermatogenesis, each primary spermatocyte undergoes meiosis and forms four functional sperm cells.
Second, oogenesis produces a larger gamete than spermatogenesis. The female gamete, or egg, is much larger and contains abundant cytoplasm to support the developing embryo. In contrast, the male gamete, or sperm, is relatively small and streamlined to facilitate motility and reach the egg for fertilization.
Third, both processes do not produce the same number of viable gametes. Oogenesis results in the formation of one viable egg cell per primary oocyte, whereas spermatogenesis produces four viable sperm cells per primary spermatocyte.
Lastly, both oogenesis and spermatogenesis are arrested at an intermediate step until puberty. In females, oogenesis is arrested at prophase I until puberty, while in males, spermatogenesis is arrested at the primary spermatocyte stage. The onset of puberty triggers the continuation of these processes.

Explanation:
Oogenesis produces a larger gamete than spermatogenesis:
- In oogenesis, the process of meiosis in females results in the formation of one large egg or ovum and two smaller polar bodies.
- The egg contains a large amount of cytoplasm and organelles needed for supporting early embryonic development.
- On the other hand, in spermatogenesis, the process in males produces four equal-sized sperm cells with minimal cytoplasm.
- Sperm cells are designed for mobility and fertilization, hence they do not require as much cytoplasm or organelles as eggs do.
- Therefore, oogenesis produces a larger gamete, the egg, compared to spermatogenesis which produces smaller sperm cells.
This statement is true because the size and function of the gametes produced in oogenesis and spermatogenesis are indeed different, with oogenesis resulting in larger gametes (eggs) compared to the smaller gametes (sperm) produced in spermatogenesis.
