Study Notes
Characteristics of Life
- Homeostasis involves maintaining a constant internal environment
- Adaptation involves the ability to adapt to the environment
Levels of Organization
- The smallest unit of life is a cell, contained within a plasma membrane
- A group of similar cells performing a specific function is called tissue
- A structure composed of more than one tissue is called an organ
- A group of organs performing a broad biological function is called an organ system
- The natural hierarchy of biological organization is: cell → tissue → organ → organ system
Taxonomy and Classification
- Taxonomy is the science that deals with the study of all living things
- Artificial classification in biology uses characteristics to identify and group organisms
- Natural organization in biology emerges from evolutionary relationships
- The purpose of taxonomy in biology is to understand and classify living organisms
- Humans are considered as Homo sapiens
- The correct order of taxonomy for modern humans is: Domain: Eukarya, Kingdom: Animalia, Phylum: Chordata, Class: Mammalia, Order: Primates, Family: Hominidae, Genus: Homo, Species: Homo sapiens
- The taxonomic level that includes ONLY Homo sapiens (modern day humans) is Species
Homeostasis
- Homeostasis is the maintenance of a constant internal environment
- In humans, body warmth is maintained through homeostasis
- The meaning of 'homeostasis' in Greek is "remaining the same"
