| Question | Answer |
|---|---|
| CELL THEORY | THREE STATEMENTS THAT DEFINE ALL LIVING THINGS IN TERMS OF CELLS. 1. ALL ORGANISMS ARE MADE OF ONE OR MORE CELLS. 2. THE CELL IS THE BASIC UNIT OF ALL LIVING THINGS 3. ALL CELLS COME FROM EXISTING CELLS |
| CELL | SMALLEST LIVING UNIT OF AN ORGANISM; MEMBRANE-COVERED STRUCTURES THAT CONTAIN ALL THE MATERIALS NECESSARY FOR LIFE |
| TISSUE | A GROUP OF SIMILAR CELLS THAT WORK TOGETHER TO PERFORM A SPECIFIC JOB |
| ORGAN | TWO OR MORE TISSUES WORK TOGETHER TO PERFORM A SPECIFIC JOB |
| ORGAN SYSTEM | GROUPS OF ORGANS THAT WORK TOGETHER TO PERFORM SPECIFIC JOBS |
| ORGANISM | ANYTHING THAT CAN INDEPENDENTLY CARRY OUT LIFE'S PROCESSES |
| MULTI CELLULAR | MEANS "MANY CELLS" |
| UNICELLULAR | ONE CELL |
| FUNCTION | THE JOB THE PART DOES |
| STRUCTURE | THE SHAPE OF A PART AND THE MATERIAL IS MADE OF |
| PROKARYOTE | ORGANISMS THAT DO NOT HAVE A NUCLEUS |
| EUKARYOTE | ORGANISMS WHOSE CELLS HAVE A NUCLEUS; MOST VISIBLE ORGANISMS ARE EUKARYOTES EX: ANIMALS, PLANTS |
| EUBACTERIA | MOST COMMON TYPE OF BACTERIA; SMALLER THAN EUKARYOTIC CELLS; NO NUCLEUS, NO MEMBRANE ORGANELLES, LIVE MOST ANYWHERE; SINGLE CELLED; DNA FORMS LOOPS; HELPS MAKE PICKLES AND YOGURT |
| ARCHAEBACTERIA | NOT AS COMMON AS EUBACTERIA; SINGLE CELLED; NO NUCLEUS AND NO MEMBRANE BOUND ORGANELLES; |
| 3 TYPES OF ARCHAEBACTERIA | HEAT LOVING, SALT-LOVING, METHANE PRODUCING |
| EUKARYOTIC | LARGEST CELLS, (10 TIMES LARGER THAN MOST BACTERIA) HAVE A NUCLEUS |
| AUTOTROPH | ORGANISM THAT MAKES ITS OWN FOOD; EX- PLANTS & ALGAE |
| HETEROTROPH | ORGANISMS WHOSE FOOD SOURCE IS OTHER ORGANISMS; EX: ANIMALS, FUNGI, BACTERIA |
| 3 TYPES OF PLANT TISSUE | TRANSPORT, GROUND, & PROTECTIVE TISSUE |
| ROBERT HOOKE | NAMED THE LITTLE BOXES HE SAW IN CORK "CELL" AFTER SEEING THEM UNDER MICROSCOPE |
| RUDOLF VIRCHOW | SCIENTIST WHO STATED THAT ALL CELLS COME FROM EXISTING CELLS |
| BIOTIC | PERTAINS TO A LIVING THING AS WELL AS ITS PRODUCTS (PLANT, ANIMAL, FUNGUS) |
| ABIOTIC | NON-LIVING EX-LIGHT, TEMPERATURE, WIND, ROCKS |
| ASEXUAL | TYPE OF REPRODUCTION THAT REQUIRES ONLY ONE PARENT AND DOES NOT MIX GENETIC MATERIAL |
| SEXUAL | WHEN TWO PARENT CELLS JOIN TOGETHER TO FORM A NEW CELL |
| ENVIRONMENT | EVERYTHING THAT AFFECTS AN ORGANISM |
| ECOLOGY | STUDY OF THE RELATIONSHIPS BETWEEN ORGANISMS AND THEIR ENVIRONMENT |
| ORGANISM | ANYTHING THAT CAN INDEPENDENTLY CARRY OUT LIFE'S PROCESSES |
| POPULATION | A GROUP OF SIMILAR ORGANISMS THAT SHARE THE SAME AREA |
| COMMUNITY | DIFFERENT POPULATIONS THAT LIVE IN THE SAME AREA |
| ECOSYSTEM | A COMMUNITY TOGETHER WITH ITS NONLIVING ENVIRONMENT |
| BIOSPHERE | ALL OF THE ECOSYSTEMS ON EARTH |
