  1. Living vs.Non-living

  2. Characteristics of Life:

  3. 1. Living things are made up of cells • Cell: Basic unit of life • Unicellular: organism made up of one cell ex. amoeba • Multicellular: organism made up of more than one cell ex. human

  4. 2. Living things reproduce. • Sexual reproduction: 2 cells from 2 different parents to produce the first cell of a new individual • Asexual Reproduction: New organism has single parent

  5. 3. Living things are based on a universal genetic code. • DNA: deoxyribonucleic acid. Traits are inherited from parents.

  6. 4. Living things grow and develop.

  7. 5. Living things obtain and use materials and energy. • Metabolism: chemical reactions that builds up or breaks down materials as an organism carries on life processes.

  8. 6. Living things respond to their environment.

  9. 7. Living things maintain a stable internal environment. • Homeostasis: process of keeping internal conditions stable

  10. 8. Taken as a group, living things change over time. • Evolution: Changes that occur in an organism over a long period of time, several generations.

  11. Biology • BIO- = life • - logy = study of The study of life!

  12. Ecology • ECO- = environment/ecosystem • -logy = study of The study of the environment or ecosystem.

  13. Zoology • Zoo- = animal • -logy = Study of The study of animals.

  14. Paleontology • Paleo- = past • -logy = the study of The study of past life.

  15. Levelsof Organization

  16. Molecules • Groups of atoms • Smallest unit of most chemical compounds

  17. Cells • Smallest functional unit of life

  18. Groups of Cells • Tissues • Organs • Organ system

  19. Organism • Individual living thing

  20. Population • Group of organisms of one type that live in the same area

  21. Community • Populations that live together in a defined area

  22. Ecosystem • Community and its non-living surroundings

  23. Biosphere • The part of the earth that contains all ecosystems
