oogamous

The large, immobile egg cell awaits the smaller, motile sperm cell in oogamous reproduction.

Definition

1. Adjective:
   • Relating to a type of sexual reproduction: "oogamous" describes a mode of reproduction in which the female gamete (egg) is large and non-motile, while the male gamete (sperm) is small and motile. This is common in many algae, fungi, and plants.

Usage Examples

• (The algae reproduce using a large, stationary egg and a small, swimming sperm.)
• (The reproductive process requires the sperm to swim to the egg.)
• (This type of reproduction shows greater specialization of gametes.)

Advanced Usage

• "Oogamous fertilization": the process of a small, motile sperm fertilizing a large, stationary egg.
  • In oogamous species, fertilization occurs when the sperm reaches the egg through water or a fluid medium. (The sperm travels to the immobile egg.)
• "Oogamous life cycle": a reproductive cycle characterized by distinct male and female gametes with size and motility differences.
  • The oogamous life cycle is typical of land plants and many animals. (This cycle involves specialized gametes.)

Variants and Related Words

• Oogamy (n): the condition or process of being oogamous; sexual reproduction involving a large, non-motile egg and a small, motile sperm.
  • Oogamy is a common reproductive strategy in multicellular organisms. (The reproductive system uses distinct gametes.)

Synonyms

• Heterogamous: involving two different types of gametes (often used interchangeably with "oogamous" but can also refer to anisogamous reproduction).
• Anisogamous: involving gametes of different sizes (a broader term; oogamy is a specific form of anisogamy where the female gamete is much larger and non-motile).
