Reproductive System (Female)
Structure and function of female reproductive organs including ovaries, oviducts, vagina, spermatheca, collateral glands, and the process of ootheca formation.
What is Reproductive System (Female)?
Functional units within the ovaries of insects where oogenesis takes place, producing eggs.
Key points
- Identify the components of the female reproductive system in a cockroach.
- Describe the function of each part of the female reproductive system.
- Explain the process of fertilization and ootheca formation.
- Understand the significance of the spermatheca and collateral glands.
Common exam trap
Confusing the function of spermatheca with fertilization.
Definitions
- Term
Ovarioles
- Meaning
Functional units within the ovaries of insects where oogenesis takes place, producing eggs.
- Term
Spermatheca
- Meaning
A sac-like organ in the female reproductive tract of insects used for storing sperm received from the male.
- Term
Collateral Glands
- Meaning
Accessory reproductive glands in female insects that secrete substances to form the ootheca.
- Term
Ootheca
- Meaning
A protective case or egg-laying structure formed by the secretions of collateral glands, enclosing fertilized eggs.
- Term
Oogenesis
- Meaning
The process of the formation and development of female gametes (ova or eggs).
