Understanding Living Things: Characteristics and Classification in Biology

Explore the fundamental characteristics that differentiate living from non-living things in this comprehensive lesson on biology. This resource covers essential components such as cell structure, reproduction, energy use, metabolism, homeostasis, genetics, evolution, and interactions within communities. Learn about the classification of life forms and the significance of binomial nomenclature for scientific naming. Engaging group activities enhance understanding, allowing students to visualize and present key biological concepts effectively.

  1. 9/12/2012Do Now Complete the hand out, you are dealing with a real REGENTS question.

  2. 9/12/2012 1. Identify the following as living or non- living. 2. What makes them living?

  3. LG: What Makes Living Things Living?LG: How are Living Things Classified?

  4. LG: What Makes Living Things Living? What is biology? • Biology is the study of living things. • Bio-: something living • -logy: the study of

  5. Terminology • Living=Biotic • Non-living=Abiotic

  6. Group Work! • Each group will receive a packet to read and analyze • After reading, each group will use color markers to create a diagram to represent assigned characteristic of living things. • Each group at the end will present to the class the main ideas

  7. LG: What Makes Living Things Living? First Characteristic of Living Things • All living things are made of one or more cells. • What is a CELL? A cell is the smallest unit that carries on the functions of life.

  8. Unicellular vs. Multicellular • Uni-: single Ex: paramecium, amoeba, some yeasts • Multi-: many (more than one) Ex: plants, human

  9. LG: What Makes Living Things Living? SecondCharacteristic of Living Things • All living things have an ability to reproduce.

  10. LG: What Makes Living Things Living? Third Characteristic of Living Things • All living things use energy. Plants however use the sunlight to obtain their energy. Animals and humans eat food to obtain their energy.

  11. LG: What Makes Living Things Living? Third Characteristic of Living Things • All living things can obtain and use energy to carry out life processes. • Ex: digest food, exercise, move around… • Metabolism: chemical reactions occur in our body to convert nutrients to ENERGY

  12. Fourth Characteristic of Living Things • All living things must maintain homeostasis. • Homeostasis: internal stability • Ex: maintain constant temperature when outside is hot or cold Normal AVERAGE body temperature: 98.6ºF

  13. Fifth Characteristic of Living Things • All living things are able to pass on their characteristics from parents to their offspring through genes.

  14. Sixth characteristic of living things • All living things can evolve.

  15. Seventh characteristic of living things • All living things can interact with each other in a community. They all depend on each other for survival.

  16. LG: What Makes Living Things Living? EighthCharacteristic of Living Things • All Living things are highly organized. • For example a group of muscle cellscome together to form our muscles. • Contain 4 types chemicals: carbohydrate, proteins, lipid (fat), nucleic acid (DNA)

  17. Living vs. Non-living

  18. Classification of Living Things • http://www.hhmi.org/coolscience/forkids/critters/critters.html

  19. 3 Domains of Life

  20. 5 Kingdoms

  21. King Philip Came Over For Good Spagetti

  22. Scientific Name • Also known as Binomial Nomenclature • Genus + Species. • ex: the scientific name for human is Homo sapiens Genus Species
