Correct answer: C. Oogamy
- A. Isogamy
- B. Anisogamy
- C. Oogamy
- D. All of the choices are correct
Explanation
Oogamy is a form of sexual reproduction found in many organisms, including plants, algae, and some animals. In oogamy, the female gamete, typically a larger, non-motile egg, is fertilized by a smaller, motile male gamete, often referred to as a sperm. The sperm typically possesses a flagellum, which allows it to swim toward the egg for fertilization. This reproductive strategy is common among many multicellular organisms, including humans, where the sperm fertilizes the egg during sexual reproduction.
