Study Notes
Common Traits of Animal Cells
- All animal cells share the ability to obtain energy from organic nutrients.
- Animal cells do not exchange materials with their surroundings, maintaining internal environments.
- Unlike some organisms, animals do not detect and respond to immediate environmental signals.
Origin of Daughter Cells in Animals
- Daughter cells originate from a single fertilized egg, which divides multiple times through the process of mitosis.
Initial State of Animals
- Animals begin life as a single fertilized egg, representing an early developmental stage before further differentiation.
Role of Homeostasis in Animal Bodies
- Homeostasis is critical for maintaining stable internal conditions, including body fluids and temperature regulation, despite external changes.
Structure and Function Relationship in Animals
- The relationship between structure and function is significant, as it dictates how various body systems operate efficiently; for instance, the form of organs like the heart contributes to its function in circulation.
Ctenophores Overview
- Ctenophores, also known as comb jellies, are marine invertebrates characterized by their distinctive features.
Function of Colloblasts in Ctenophores
- Colloblasts are specialized cells in ctenophores responsible for capturing prey using sticky secretions, aiding in their feeding strategy.
Significance of Cilia in Ctenophores
- Cilia in ctenophores play a crucial role in locomotion and feeding, allowing them to move through water and transport food to their mouths.
Gut Features in Ctenophores
- Ctenophores possess a unique digestive system with a gut that is branched, providing a larger surface area for nutrient absorption.
Arrangement of Nerve Cells in Ctenophores
- Nerve cells in ctenophores are organized in a decentralized nerve net rather than a centralized brain, enabling coordinated movements and responses.
