|---|
| Reproduction | process of copying a living organism to make offspring |
| asexual | reproduction by a single parent to produce identical offspring |
| examples of asexual creatures | amoeba, bacteria |
| sexual | reproduction by two parents and producers offspring that are different |
| egg contains | genetic material (DNA) and food supply |
| fertilization | process in which the sperm joins the egg |
| zygote | fertilized egg |
| growth | increase in the amount of living material that an organism has |
| growth increases | number of cells, size of cells |
| development | series of changes that organisms go through in order to reach the final adult form |
| homeostasis | maintaining propper conditions for internal functions |
| homeostasis conditions | body temp., heart beat, water balance, PH (normaly 7) |
| organization | precises what all the parts fit together to create an orderly living system |
| organization parts | cell parts, body tissues, organs and grgan systems |
| energy | the ability to do work |
| work | anything that causes motion either internal or external physical or chemical |
| producers | autotroph, organisms in the community that manufacture food |
| sunlight | source of energy |
| chlorophyll | green pigment in plants that traps the energy from the sun |
| carbon dioxide and water | raw materials from the environment |
| sugar | product that green plants make |
| consumers | organisms that cant make there own food so they must feed on other organisms |
| primary | eat producers |
| secondary | eat consumers |
| decomposers | feed on remains of dead plants and animals or there waste products |
| food chain | passage of energy from organism to organism from producers to consumers to decomposers |
| cellular respiration | process that organisms undergo releases engergy from food materials gives off CO2 and H20 |
| unity | things that all organisms have in common |
| all organisms have .... in common | basic life functions, need for energy |
| diversity | variation among organisms |
| evolution | change in organisms over time |
| taxonomy | system of classifying living organisms |
| community | assortment of life lving together in a particular place and interacting and depending in various ways |
| science | process that introduces a body of knowledge about nature |
| technology | applying knowledge to solve problems |
| process of technology includes: | observation, interpretation, explanation, and testing |
| problem | generally what the scientist is trying to find out as a result of what he or she has seen in nature |
| hypothesis | formal statement writen in an if/then format, very specific, indicates what the scientist will investigate |
| materials | things needed to preform the experiment |
| procedure | steps that tell you how to do your experiment |
| control | part of the experiment that remains constant |
| independent variable | experimental groups with the dieff. conditons being tested |
| dependent variable | data that results from testing the experiment |
| specifications | number of trials, how many in the group, type of measurment |
| data table | prepare your data table ahead but labels on it and write down the units |
| measurments | observe your experiment, get your numbers |
| record | write down the data |
| relationships | differances and similarites between trials and between controls |
| visualizations | make or draw a graph |
| types of graphs | line, bar, or pie |
| interpretaion | explaining the graph, stating what the graph shows you |
| conclusion #1 | use your data and your analysis to account for the cause |
| conclusion #2 | relate the conclusion back to the hypothesis |
| conclusion #3 | use logic reasoning |
| conclusion #4 | extend beyond this experiment to either predict or sugest a new experiment |
| resolving power | ability of a microscope to distinguish two objects as being seperate of eachother |
| resolving power depends on... | the magnifications and the type of microscope |
| compound light microscope | uses glass lenses, light passes through the objects, magnifies max of 2000 times, resolutions is 500nm |
| transmission electron microscope | uses magnets, uses electrons, sample must be frozen or imbeded in plastic, magnifys up to 200,000 times, resolutions is .2nm |
| scanning electron microscope | uses magnets, electrons bounce off the image not pass through it, produces 3-D image, lower magnifications, gives important info about shape and surface |
