Study Notes
Gastrodermis
- A layer of tissue in cnidarians that lines the gastrovascular cavity.
- Functions in digestion and nutrient absorption.
GVC (Gastrovascular Cavity)
- A central cavity in cnidarians for digestion and circulation.
- Serves as both a digestive system and a circulatory system, facilitating nutrient transport.
Ovary/Testes
- Reproductive structures found in hydras.
- The ovary is located at the bottom of the organism, involved in producing eggs.
Mesoglea
- A jelly-like substance found between the epidermis and gastrodermis in cnidarians.
- Provides structural support and helps in buoyancy.
Bud
- An asexual reproductive structure in hydras.
- Budding allows hydras to produce offspring that develop on the parent organism before detaching.
Cnidocyte
- Specialized cells unique to cnidarians, responsible for capturing prey.
- Contains a stinging organelle called a nematocyst.
Nematocyst
- A defensive or feeding structure found within cnidocytes.
- Discharges a barbed thread to inject venom into prey or as a defense mechanism.
Epidermis
- The outer layer of cells in hydras, providing protection and structure.
- Responsible for sensory perception and interaction with the environment.
