GUIDED NOTES-CHARACTERISTICS OF LIFE 1 In order to be considered a living thing, how many characteristics of life must an organism have? Must all organisms have the ability to obtain and use energy? Why do organisms require food? How do all living things get or release energy stored in food? What are some reasons that organisms need to obtain energy? What happens if a cell is unable to maintain organization? Ultimately, all the energy found in food came from where? What are autotrophs and do they obtain their food? How do autotrophs make their own food? What process in plants makes food? What are heterotrophs and how do they obtain their energy? Do both heterotrophs and autotrophs need to break down food to release energy for use? What process in cells breaks down food molecules for the purpose of releasing energy for use? Why is reproduction essential? What does reproduction pass onto offspring? What are the two types of reproduction? What is sexual reproduction? What is the first cell of new offspring called? What does sexual reproduction produce and why is this important? What is asexual reproduction? Does asexual reproduction create variation? All organisms begin life as how many cells? How do multicellular organism grow and by what process? Does growing require energy? What is development? What is differentiation? Do all cells in an individual have same exact DNA, even specialized cells? How do cells become specialized?
