3 VOCAB ASSIGNMENTEVERY 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 Characteristics of Life!!!!!! How do you know if an object is ALIVE?It has to have ALL SevenCharacteristics 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 SMALLESTLIVING UNIT THAT CAN CARRY OUT LIFE PROCESSESSCALE 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 muscleNerve cellLeaf cellRed Blood CellYeast 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 wordMulticellular= 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.HETEROTROPHicConsumers (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 Stimulia. 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 Reproduction1. Budding – Hydra and Sponge2. Fragmentation - Starfish3. Binary Fission – unicellular organisms
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).
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? ReproductionCellsAdaptationGrow and developResponsesEnergy
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, unicellular5. Define: prokaryotic cell, eukaryotic cell6. Define: taxonomy, classification, kingdom, organism
26 FLASH CARD GAME! WE WILL FORM TWO TEAMS EACH TEAM IS COMPETEING AGAINST THE OTHER FOR EXTRA CREDITTEACHER WILL CALL ON ONE TEAM MEMBER FROM EACH TEAMTHE TWO STUDENTS WILL USE A WHITE BOARD TO WRITE OUT:L = LIVINGD = DEAD/ ONCE-LIVINGN = NON-LIVING
27 Vocab unit 1-flash back Write in your vocab section of spiral ntbk Unicellular- one celled organismsIn multi-cellular animals, the cells will perform specific jobs (bone cells, skin cells)Heterotrophic- animals that must eat other plants or animals for their foodAutotrophic-organisms that can make their own foodHomeostasis-keeping conditions inside the body constant (example: temperature)
