[object Object],[object Object],[object Object],[object Object],[object Object],carry out all life processes respond/react to changes in the internal and external environment converting food energy into usable energy (ATP) Organisms ability to maintain a constant internal environment

[object Object],[object Object],[object Object],Increasing the size of the organism Producing offspring, increasing the number of organisms; necessary for the survival of the species, not an individual Removal of metabolic wastes from organism

[object Object],[object Object],[object Object],[object Object],obtaining or producing food movement of materials throughout the organism Combining smaller units to Produce larger molecules

[object Object],[object Object],[object Object],[object Object],[object Object],The first cell on Earth could not have come from another cell Viruses Cannot reproduce on their own, require a host cell Mitochondria and chloroplast Are not considered living because they don’t carry out all life processes are not considered living because they do not perform all life processes
