Explanation:
Definition of Oogamy:
Oogamy is a form of sexual reproduction in which the female gamete is significantly larger and non-motile compared to the smaller, motile male gamete.
Fertilization in Oogamy:
In oogamy, fertilization involves the fusion of the large non-motile female gamete (egg) with the small motile male gamete (sperm). This is because the female gamete carries most of the cytoplasm and organelles necessary for the development of the zygote, while the male gamete is responsible for delivering the genetic material.
Role of Female Gamete:
The large non-motile female gamete provides the nutrients and cellular machinery needed for the early stages of development after fertilization. It contains a large amount of cytoplasm, mitochondria, and other organelles that support the growth and division of the zygote.
Role of Male Gamete:
The small motile male gamete, on the other hand, is designed for mobility and delivering its genetic material to the egg for fertilization. Its main function is to provide the genetic material (DNA) to combine with the genetic material of the egg to form a new individual.
Conclusion:
Therefore, in oogamy, fertilization involves the fusion of a large non-motile female gamete with a small motile male gamete, as this arrangement allows for the efficient transfer of nutrients and genetic material for the development of the zygote.
