  1. Let’s Practice State if the object is living or nonliving. Nonliving Living Nonliving Living Living

  2. The characteristics of life.

  3. A CELL IS THE SMALLESTLIVING UNIT THAT CAN CARRY OUT LIFE PROCESSES. 1. ALL LIVING THINGS ARE MADE OF CELLS

  4. Single celled (unicellular ) organisms makeup most organisms on Earth. They have everything they need to be self-sufficient. In multi-cellular organisms, the cells specialize to perform specific functions (bone cells, skin cells, muscle cells, root cells, leaf cells).

  5. The processes of life.

  6. 2. Take in nutrients to create energy/respire Nutrients = Food, water, air Producers (Plants) trap the energy of the Sun and make food in the process called photosynthesis. Consumers(animals) get their nutrients from the producers or other consumers!

  7. A process in which organisms use the oxygen in the air to turn food into energy. In order to get the energy, all living thing go through cellular respiration-

  8. Animals move their whole bodies to get from one place to another. Plants turn towards the light and their roots grow down into the soil. 3.All living things move !!

  9. excrete-to remove waste substances from the body. Plants and animals both need to get rid of waste gas and water. 4. All living thingsproduce waste!!

  10. 5. ALL LIVING THINGS RESPOND TO A STIMULUS Living things respond to immediate and long-term changes in their environment (shiver when cold, change fur color, plants bend toward light). Why is this important? Homeostasis-organism must be able to make constant adjustments to maintain stable conditions no matter what is occurring inside or outside of organism, if not survival decreases

  11. a. dogs pant when hot b. humans sweat when body gets too hot c. pupils dilate in lower light levels d. reflexes – touch hot stove, fight/flight Responding to Stimuli

  12. 6. ALL LIVING THINGS ADAPT TO FIT THEIR ENVIRONMENT Organisms must adapt to changes in their environment or risk becoming extinct. Adaptations occur over a very long period of time (millions of years). https://www.youtube.com/watch?v=YX8VQIJVpTg

  13. Name some the adaptations of these organisms.

  14. Animals have babies. New plants grow from seeds. 7. ALL LIVING THINGS REPRODUCE Reproduction must occur for a species to survive.

  15. 8. ALL LIVING THINGS GROW AND DEVELOP (The life cycle) To grow means to get bigger and to get bigger Develop means to change into an adult form (mature). Living things die

  16. WHAT DID YOU LEARN? • Define: living, dead, nonliving. * Living organisms must show ALL characteristics of life. *Dead organisms ONCE showed ALL characteristics but now do not. *Nonliving things do not have all characteristics. 2. Define: multicellular, unicellular Multicellular- more than one cell. Unicellular – made of only one cell 3. What are the 8 characteristics of life?

  17. The characteristics of life. • Made of Cells • Get nutrients for energy/Respire • Move • Create Waste/ Excrete • Respond to environment • Adapt • Reproduce • Grow/Develop (life Cycle)
