  1. 7 Characteristics of Life

  2. VOCABULARY A - Not Moral vs. AMORAL AUTO – one or by itself AUTOMOBILE AUTOBIOGRAPHY BI - two BICYCLE BILINGUAL BIOLOGY BIO – life HETERO – different or other heterogeneous MULTI - many MULTITASK MULTITALENTED NONSMOKING NONEXISTENT NON - not UNI - one Unicycle Unicorn

  3. VOCAB ASSIGNMENT • EVERY UNIT, YOU WILL BE ASSIGNED A LIST OF VOCABULARY WORDS. THE TEACHER WILL GIVE YOU THEIR DEFINITIONS. • IT IS YOUR JOB TO FIND AT LEAST TWO EXAMPLES OF THAT VOCABULARY WORD BEING USED (MOST LIKELY YOU WILL FIND ALL OF YOUR EXAMPLES FROM CLASS). • WRITE THE EXAMPLES IN YOUR SPIRAL NOTEBOOK

  4. How do you know if an object is ALIVE? It has to have ALL Seven Characteristics of Life!!!!!!

  5. Let’s learn about the 7 characteristics of life.

  6. 1) ALL LIVING THINGS ARE MADE OF CELL(S) A CELL IS THE SMALLEST LIVING UNIT THAT CAN CARRY OUT LIFE PROCESSES SCALE OF CELLS

  7. Single celled (unicellular ) organisms-Organisms that are made up of only one cell. They have everything they need to be self-sufficient.

  8. In multi-cellular animals, the cells will perform specific jobs (bone cells, skin cells, muscle cells, root cells, leaf cells). Smooth muscle Nerve cell Leaf cell Red Blood Cell Yeast cell

  9. 2) ALL LIVING THINGS USE ENERGY TO MAINTAIN HOMEOSTASIS The SUN is the main source of energy on Earth!!! The Sun makes light that is used by plants!!!!!! What is the name of this process by which plants convert the energy from the sun into food?

  10. #2 vocab word • Multicellular= animals w/more than one cell

  11. Homeostasis-  is the ability to maintain a constant internal environment in response to environmental changes.

  12. Plants (producers) trap the energy of the Sun and make glucose (sugar) in the process called photosynthesis. AUTOTROPHIC organisms can make their own food

  13. 4.HETEROTROPHic Consumers (animals) get their energy from the plants!!!! Can’t make their own food!

  14. 3) ALL LIVING THINGS RESPOND TO A STIMULUS (plural-Stimuli) Living things respond to immediate and long-term changes in their environment (shiver when cold, change fur color, plants bend toward light).

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

  16. 4) ALL LIVING THINGS REPRODUCE • Reproduction must occur for a species to survive. Reproduction can be either sexual or asexual.

  17. ASEXUAL REPRODUCTION -Reproduction by one parent 3 Types of Asexual Reproduction 1. Budding – Hydra and Sponge 2. Fragmentation - Starfish 3. Binary Fission – unicellular organisms

  18. ASEXUAL REPRODUCTION

  19. 5) ALL LIVING THINGS GROW AND DEVELOP To grow means to get bigger and to get bigger; more cells must be added. To increase numbers of cells, cell division must occur. Develop means to change into an adult form (mature).

  20. 6) ALL LIVING THINGS CHANGE TO FIT THEIR ENVIRONMENT(ADAPT) Organisms must adapt to changes in their environment or risk becoming extinct. Adaptations occur over a very long period of time (millions of years).

  21. Name some the adaptations of these organisms.

  22. 7) ALL LIVING THINGS HAVE DNA. DNA provides instructions for LIFE. making molecules called proteins. Proteins build cells. DNA carries the genetic material from parent to offspring (heredity).

  23. LET”S PRACTICE!!! Which characteristics of life is being described? Reproduction Cells Adaptation Grow and develop Responses Energy

  24. Bellringer: Give an example of something living, dead and nonliving. * Living organisms must show ALL 7 characteristics of life. *Dead organisms ONCE showed ALL 7 characteristics but now do not. *Nonliving things do not have all 7 characteristics.

  25. BELLRINGERS • Define: living, dead, nonliving. 2. Give examples of living, nonliving and dead objects. 3. Describe how you would know if an object is living or nonliving? 4. Define: multicellular, unicellular 5. Define: prokaryotic cell, eukaryotic cell 6. Define: taxonomy, classification, kingdom, organism

  26. FLASH CARD GAME! • WE WILL FORM TWO TEAMS • EACH TEAM IS COMPETEING AGAINST THE OTHER FOR EXTRA CREDIT • TEACHER WILL CALL ON ONE TEAM MEMBER FROM EACH TEAM • THE TWO STUDENTS WILL USE A WHITE BOARD TO WRITE OUT: L = LIVING D = DEAD/ ONCE-LIVING N = NON-LIVING

  27. Vocab unit 1-flash back Write in your vocab section of spiral ntbk • Unicellular- one celled organisms • In multi-cellular animals, the cells will perform specific jobs (bone cells, skin cells) • Heterotrophic- animals that must eat other plants or animals for their food • Autotrophic-organisms that can make their own food • Homeostasis-keeping conditions inside the body constant (example: temperature)
