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.
