CHAPTER 6 CLASSIFYING LIVING THINGS Chapter 6 Ways That Living Things Perform Functions Grow: Unicellular organisms- size of their cell increases Multicellular organisms- # of cells increases Develop: Ladybug larvae grow into a pupae and then adults Use Energy: Autotrophs: Convert light or energy into food Heterotrophs- obtain energy from other organisms Respond to Stimuli: Octopus responds to predators by releasing ink to protect itself What Do Living Things Need? Sunlight/Energy(food) H20 CO2 & O2 Living Space Proper Temperature HW DUE 1/5: Re read pgs. 187-193. Choose ONE living thing. Choose ONE life function-Write ONE paragraph explaining how the function applies to the organism. How are they related? HOMEWORK 1/9 In your own words, define PROKARYOTIC and EUKARYOTIC Name the functions of the following: cell membrane, cell wall, nucleus, cytoplasm, mitochondria, chloroplast Answer After Reading 1. 2. 3. 4. 5. What are cells made of? What do many egg cells look like? Why is a microscope needed to view most cells? What would happen to a human’s cells if the human becomes dehydrated? Do you think each of the trillions of cells that are a part of you are either alive or once-living? Why? WHAT ARE LIVING THINGS? 6 Functions Made of cells Organized Grow and develop Respond to their environment • Reproduce • Use Energy • • • • 5 Life Needs • • • • • CO2 & O2 H2O Food & Sunlight Living Space Proper Temperature Lesson 1 Vocabulary Autotroph: organism that converts light energy into usable energy Habitat: specific environment where an organism lives Heterotroph: organism that obtains energy from other organisms Macromolecule: Substance in a cell that forms from joining many small molecules together Unicellular: one- celled organism Multicellular: an organism made of more than one cell Do NOW Friday, January A 10, 2014 cell is : A eukaryotic cell is: A prokaryotic cell is: A human cell is prokaryotic OR eukaryotic??? Identify the missing organelles A - Cell membrane B - Nucleus C - Ribosome D - ER E - Mitochondria F - Nuclear Membrane Organelles & Functions Cell membrane - protects the cell , controls what comes in and out of the cell Nucleus - directs cell activities(BRAIN) ER (Endoplasmic Reticulum)- sends messages(HIGHWAY)/where some ribosomes are found Golgi Body – packages proteins to be delivered around the cell(mailmen) Ribosome - makes proteins Mitochondria - produces energy(Powerhouse!) Lysosomes-Clean out waste in the cell (garbage men) Vacuoles- stores food, H2O, and O2 (warehouse) Cytoplasm- jelly-like substance in the cell REMEMBER! PLANT CELLS HAVE 2 ORGANELLES THAT AN ANIMAL CELL DOES NOT: CELL WALL AND CHLOROPLAST Friday, January 17th • • • • • • MVCO! Most Valuable Cell Organelle Choose any organelle and connect it to one of the 6 life functions: Made of cells Organized Grow and develop Respond to their environment Reproduce Use Energy USE YOUR NOTES AND TEXTBOOKS TO REFER TO ORGANELLES AND FUNCTIONS MVCO Example: A golgi body is related to RESPONDING TO THE ENVIRONMENT BECAUSE…… Must use COLOR and DECORATION/ILLUSTRATION Photosynthesis Carbon Dioxide + Water (with sunlight and chlorophyll)----glucose(sugar) + Oxygen 6CO2 + 6H20----- C6H12O6 +6O2 Chlorophyll TRAPs energy from the sun and converts in into chemical energy OCCURS ONLY IN PLANTS Why???? ONLY PLANT CELLS HAVE CHLOROPLAST Cellular Respiration Glucose + Oxygen--- Water + Carbon Dioxide + ATP(energy) C6H12O6 + 6O2-- 6H2O + 6CO2 + ATP Takes in place in BOTH plant and animal cells IN THE MITOCHONDRIA ****Mitochondria breaks down the sugar and releases energy!!!!!!
