CLASSIFYING LIVING THINGS 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 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 5 Life Needs Made of cells Organized Grow and develop Respond to their environment Reproduce Use Energy 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

A human cell is prokaryotic OR eukaryotic??? Do NOW Friday, January 10, 2014 A 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

USE YOUR NOTES AND TEXTBOOKS TO REFER TO ORGANELLES AND FUNCTIONS 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!!!!!!
