Study Notes
Classification of Animals
- Animals are categorized into 35 major groups known as phylums, which are broader than classes.
- Classes are more specific groupings within phylums, allowing for a more precise classification of organisms.
Key Factors for Classification
- Classification of animals relies on three primary aspects:
- Body Structure: Physical characteristics and anatomy of the animal.
- Development: The process of growth and maturation from embryo to adult.
- DNA: Genetic makeup that provides insights into evolutionary relationships.
Main Functions of Animals
- Animals perform four essential functions:
- Obtaining Food and Oxygen: Essential for survival and energy production.
- Maintaining Internal Stability: Homeostasis is crucial for regulating internal environments.
- Movement: Allows animals to navigate their environment and interact with others.
- Reproduction: Vital for the continuation of species and genetic diversity.
