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.
