| Living things are organized | made of cells |
| each cell has | an orderly structure |
| each cell also has | hereditary information |
| organisms are made . . . | of one, a few, or many cells |
| Living things respond by . . . | interacting with their environment |
| Living things respond | respond to a stimulus |
| must respond to stimuli from . . . | outside and inside body |
| Living things respond - need to maintain . . . | homeostasis |
| homeostasis | organism keeps internal environment within range needed for survival |
| examples of homeostasis | body temperature, blood sugar, blood volume |
| Living things use energy to . . . | to do things and stay organized |
| Living things get energy from . . . | food or directly from sun |
| Living things; energy can come from . . . | photosynthesis |
| photosynthesis definition | creates high energy molecules (sugars) from CO2, H2O, and sunlight |
| Living Things grow and develop | by adding cells and changing body |
| Grow/Develop - how does a puppy grow? | Take in raw materials (food) |
| Growth & development happens by . . . | making more cells (cells do not get larger – still very small) |
| definition of development | changes that take place in organism as they grow |
| Living things reproduce | some bacteria – can reproduce in 20 min |
| Living things reproduce | make more copies of self |
| Living things reproduce | can be asexual or sexual |
| Populations of living things . . . | evolve |
| Evolution definition | is the change in a population or species over time |
| Over time, evolution can create . . . | a new species |
| in population, there are many | tiny difference between individuals |
| Some of those differences (by chance) will help | that individual reproduce more successively |
| Individuals who reproduce more successively will | pass on those differences to their offspring |
| Over generations, those differences in the population that are an advantage in helping individuals reproduce successively will | increase in the population |
| Over generations, the population will change to become better | at surviving and reproducing in the environment they are living in |
