  1. What is Biology?

  2. Biology- natural science concerned with the study of life and living organisms • Fundamental concepts of modern biology 1. Cells are basic unit of life

  3. 2. New species and inherited traits are the product of evolutionary change

  4. 3. Genes are the basic unit of heredity

  5. 4. Organisms regulate internal environments to maintain a stable and constant condition Homeostasis

  6. 5. Living organisms consume and transform energy

  7. Characteristics of Life • Homeostasis: regulation of the internal environment to maintain a constant state • Organization: being structurally composed of one or more cells

  8. 3. Metabolism: transformation of energy by converting chemicals and energy into cellular components (anabolism) and decomposing organic matter (Catabolism)

  9. 4. Growth and development: growing organism increases in size in all of its parts, rather than simply accumulating matter

  10. 5. Adaptation: Ability to change over time in response to the environment

  11. 6. Response to Stimuli

  12. 7. Reproduction: The ability to produce new individual organisms
