Study Notes
Biological Organization
- An organism is a living individual made up of interconnected parts that interact to perform functions necessary to sustain life.
Emergent Properties
- A property that emerges at each level of biological organization only when the parts interact in a wider whole.
- The whole is greater than the sum of its parts.
- New attributes or characteristics emerge at each level of organization that are not present in the lower levels.
Hierarchy of Biological Organization
- Cells are the basic unit of life, and are capable of using energy to sustain themselves.
- Tissues are groups of cells that work together to perform a function.
- Organs are groups of tissues that work together to perform a function.
- Organ systems are groups of organs that interact to perform a function.
- Organisms are made up of organ systems.
Cells
- Cells in multicellular organisms differentiate to take specific shapes and perform specific functions.
Tissues
- There are four basic types of tissue in humans: connective, epithelial, muscle, and nerve tissue.
- Tissues contain more than one type of cell that work together to perform a function.
Organs
- Organs contain more than one type of tissue and work together to perform a function.
Organ Systems
- Examples of organ systems include the nervous system, skeletal system, respiratory system, and circulatory system.
Integrations of Body Systems
- The organs of animal bodies are integrated to form a functioning whole.
- Integration involves effective communication and the transport of materials and energy.
- The endocrine system and nervous system work together to maintain body processes.
