| Question | Answer |
|---|---|
| Osmosis | the diffusion of water |
| diffusion | the movement of molecules from high to low |
| photosynthesis | the process by which plants capture the light and make their own food |
| cellular respiration | the process by which the cell uses the food (glucose) to make energy |
| reactants of photosynthesis | carbon dioxide (c020 + water (h20) |
| products of photosynthesis | glucose (c6h12o6)+oxygen(o20 |
| products of cellular respiration | carbon dioxide(c02)+water(h20) |
| reactants of cellular respiration | glucose(c6h12o6)+oxgen(o2) |
| how photosynthesis and cellular respiration help each other | we breathe in oxygen and let out carbon dioxide plants take in carbon dioxide and let out oxygen |
| mitosis | the six stage process by which a eukaryotic cell makes more cells |
| interphase | the stage where chromosomes are long and stringy like spaghetti |
| prophase | the stage where chromosomes condense and shorten like ziti |
| metaphase | the stage where chromosomes line up in the middle of the cell |
| anaphase | the stage where chromosomes separate to opposite ends of the cell like spiderman |
| telophase | the phase where the cell membrane begins to spilt and the cell late begins to form |
| cytokinesis | the stage where the cell membrane completely splits into to and makes more cells |
| evolution | the process by which organisms inherit changes over time |
| fossils | solidified remains or imprints |
| vestiges structures | a once useful structure in an organism |
| comparing organisms | comparing organisms to see simalrites among other organisms |
| skelital structures | dolphin flipper, bat wing, humanarm, cat leg |
| dna | all organisms have different dan but similar codes |
| embryonic structures | when an organism grows over time |
| overproduction | to produce more offspring |
| genetic variation | same populations but different species |
| struggle to survive | favorable traits, reproduce, species |
| successful reproduction | organisms help others survive |
| why do scientists classify organisms | its more organized and easy for people to use around the world |
| carleus leinuss | named things by the modern system of classification and created taxonomy |
| taxonomy | the science of classifying organisms |
| 7 stages of classification | kingdom, phylum, class, order, family, genus, species |
| summarize the peppered moth story | there were 2 moths a dark moth and a white moth and a the birch tree the white moth always camouflaged but then there was a industrial revolution and made the trees dark so now they were camouflaged from the predators |
| speciation | the process by which two species become so different that they no longer interbreed |
| separation | portion of pollution is physically isolated (earthquake) |
| adaption | when an environment changes so does population (natural selection) |
| division | over generations the two groups of a population can become so different that they are no longer the same species |
| species | a kind of animal inside of a main animal |
| how scientists use fossils for evidence of evolution | they use layers of sediment to determine the relative age |
| the rules of of scientific naming | genus always capitalized and species lowercase it has to be underlined or italicized |
| how to use a dichotomous key | |
| six kingdoms | plant, animal, protist, eubacteria, archaebacteria, fungi |
| animal example | eagle, beatle, dolphin |
| plant example | sequis, flowering plants |
| protist example | protozoa, algae, slime mold, water mold |
| fungi example | molds and mushrooms |
| eubacteria example | e.coli and yogurt |
| archaebacteria example | hot springs |
| animal reproduction | sexual- sperm fertilizes egg (fertilization) asexual- budding part of organism buds off regeneration anew part of grows off of an old one like a starfish |
| plant reproduction | sexual- sperm in egg fertilizes egg (pollination) asexual- vegetative propagation ; runners; platelets; budding |
| protist reproduction | sexual- on conjunction exchange dna and split paramecium asexual- binary fission paramecium euglena amoeba algae |
| fungi reproduction | asexual- spores sexual- spores |
| eubacteria reproduction | asexual- binary fission |
| archaebacteria reproduction | asexual- binary fission |
| animal energy | consumers |
| plant energy | producers |
| fungi energy | decomposers |
| animal cell type | eukaryotic cell |
| plant cell type | eukaryotic cell |
| protist cell type | eukaryotic cell |
| fungi cell type | eukaryotic cell |
| eubacteria cell type | prokaryotic cell |
| archaebacteria cell type | prokaryotic cell |
| plant like protist | euglena and algae chloroplasts for food euglena also animal like flagellum |
| animal like protist | paramecium and amoeba paramecium uses hair like cilia for movement amoeba uses persudopod for movement and to capture food |
| fungi like protist | slime mold and water mold decomposers for food reproduces by spores |
| three main shapes of of bacteria | cocci, bacillus, and sprilla |
| where eubacteria maybe found | mild conditions |
| where archaebacteria maybe found | extreme conditions |
| which bacteria s the oldest | archebacetria 3.5 billion years old |
