Term | Definition |
---|---|
passive transport | particles move through cells from an area of high concentration to low concentration- no energy required |
active transport | particles move through cells from an area of low concentration to high concentration- requires energy |
endocytosis | large particles enter the cell |
exocytosis | large particles exit the cell |
photosynthesis | process by which plants capture light energy and use it to make food for the cell |
photosynthesis reactants | carbon dioxide, water + sunlight |
photosynthesis products | glucose and oxygen |
cellular respiration | process by which the cell uses food (consumed or produced) and converts it into energy |
cellular respiration reactants | glucose and oxygen |
cellular respiration products | carbon dioxide, water and ATP |
mitosis | six stage process by which eukaryotic cell divides to make more cells |
step of mitosis | interphase, prophase, metaphase, anaphase, telophase, cytokinesis |
fossil | solidified remains of once living organisms |
natural selection | process by which organisms with favorable traits survive and reproduce at a greater rate |
stages of natural selection | overproduction, genetic variation, struggle to survive, successful reproduction |
extinction | species dies out completely because they don't have the resources or adaptations to survive |
adaptations | characteristics that help organisms survive and reproduce in its environment |
vestigial structures | remains of once useful structures in organisms |
7 levels of classification | kingdom, phylum, class, order, family, genus, species |
taxonomy | the science of classifying organisms |
classification | a system of organizing things into groups based on shared characteristics and evolutionary relationships |
Carolus Linneaus | founded the modern system of taxonomy |
binomial nomenclature | scientific naming; organisms named by their genus and species |
dichotomous key | tool that uses pairs of statements to determine the identity of unknown organisms |
six kingdoms | plant, animal, fungus, protist, eubacteria, archaebacteria |
animal kingdom | includes humans, lions, butterflies etc.; consumers |
plant kingdom | includes flowers, trees, grass etc.; producers |
fungus kingdom | includes mold, mushrooms; decomposers |
protist kingdom | includes amoeba, euglena, paramecium; can be plant-like, animal- like or fungus-like |
eubacteria kingdom | most common type of bacteria; live in mild conditions |
archaebacteria kingdom | bacteria that live in extreme conditions |
amoeba | protist that uses pseudopods for movement |
euglena | protist that uses flagellum for movement |
paramecium | protist that uses cilia for movement |
