Study Notes
Characteristics of Living Organisms
- Living organisms must be able to pass on traits to future generations.
- Characteristics of life include: organization/order, adaptations, response to the environment, regulation and excretion, energy processing, growth and development, and reproduction.
Cell Structure
- All life is organized into fundamental units called cells.
- A cell is a membrane-bound structure containing organic molecules.
- Cells are microscopic in size.
Classification of Organisms
- Classification is a method of organizing species into groups.
- The modern system of classification can be complex and include 8 levels.
- Carolus Linnaeus began the modern system of classification in 1735.
- Linnaeus based his classification of species solely on shared characteristics.
- Scientists have refined this system using molecular and DNA evidence.
Kingdoms of Life
- Most large organisms are either plants or animals.
- The distinction between the plant and animal kingdoms is based primarily on the sources of nutrition and the capability of movement.
- The Kingdom Plantae is a distinct group of organisms.
Homeostasis
- Homeostasis is the regulation of an organism's internal environment.
Classification Levels
- The modern system of classification includes 8 levels.
