Exam (midterm)
| Side A | Side B |
|---|---|
| study of living things + their environment | ecology |
| study of fungus | mycology |
| study of plants | bontony |
| occurs when a species makes more of itself | reproduction |
| the passing of traits from parent to offspring is called... | inheritance |
| _____ occurs when an org. changes or becomes more complex during its lifetime | development |
| the study of animals | zoology |
| scientists use the _____ system of measurement | metric system (SI) |
| the question you're attempting to answer in an experiment | problem |
| applied science used to better the human condition (often called ____.) | technology |
| hypothesis-- | an educated guess to your problem |
| homeostasis-- | the avility of an org. to maintain the same state /condition internally |
| stimuli-- | any change in an org.'s environment |
| inheritance-- | the passing on of traits from parent to offspring |
| adaptation-- | when a species/org. becomes better adapted to its environment over time + it becomes more successful |
| What are the 3 major types of science? | Earth(studies earth + space), Physical(studies matter + energy or chemistry + physics), + Life(studies living organisms; biology) |
| 3 principles of science: | Natural causality(physical events have a phys. cause), Law of Uniformity(phys. processes are same now as were in teh past), + Law of Common Perception(humans perceive stimuli the same) |
| 3 reasons we study biology... | 1)b/c it's cool; 2)because we are made to; 3)b/c we are alive |
| List the steps of the scientific method. | Observe, define a problem, hypothesis, test, collect data, conclusion, report + share |
| 3 reasons why msrmts. are used in science... | makes experiment more accurate, lowers amt. of bias in experiment, improves communication |
| List in order the steps of biological organization. | cells(bacteria) --> tissues(jellyfish) --> organs(roundworm) --> organ system(ppl., organisms) |
| 4 necessary parts of a good or "controlled" experiment | have a control, control your variables, msrmt.(tools), repeats of your exprmt. |
| theory-- | explanation continually supported by observation + experimentation |
| law-- | a promoted theory (that hasn't been proven wrong) |
| List 4 of the 8 recurring themes found in biology. | Circle of Life(idea that all life is connected), Structure & Function(how it's built is directly related to what it does), Untiy + Diversity(most of life is very similar, but the minor diff, account for the diff. species), Organization of Life |
| the space inside of the cell | cytoplasm |
| The __ are filled with pigments in plant cells + are used to attract animals | chromoplasts |
| _____ wrote the Cell Theory | Virchow |
| Chromatin is made up of ____ and _____. | protein and DNA |
| _____ actually make the proteins | ribosomes |
| The ___ is found in plant cells and is used to store starch. | leucoplast |
| ____ is the protein-rich fluid in the cell space | cytosol |
| In plants, the ____ is used to make glucose | chloroplast |
| nuclear envelope/membrane | s= dbl membrane with a tight inner and loose outer membrane (w/ pores where they fuse) f= for protection |
| nucleolus | s=condensed areas of chromatin f=make robosomes |
| RER | s=highly folded membrane embedded with ribosomes f=to build proteins |
| SER | s=highly folded membrane f=package (vesicle) and temporarily store protein |
| Golgi Apparatus | s=highly folded membrane embedded with enzymes f=open vesicle, add finishing touches to protein, re-package protein and send it where it is needed |
| vesicle | s=membrane bound sac f=transports (exports) protein inside cell |
| vacuole | s=membrane bound sac f=for storage |
| cytoskeleton | s= microtubules made of protein f= for support (from/by protein), transport protein (within cell) |
| mitochondria | s=kidney-bean-shaped outer membrane with a highly folded inner membrane embedded with enzymes f=convert glucose (cell food) to ATP (Adenosine triphosphate/cell energy) |
| lysosome | s=membrane bound sac filled with enzymes f=recycle old, damaged, worn out cell parts |
| List 3 structural diff. b/t plant and animal cells. | 1.Plant cells have a cell wall and cell membrane 2.Plant cells have a larger vacuole to store more H2O b/c they make their own food 3. Plants have plastids (chloroplasts, leucoplasts, chromoplasts) |
| State the Cell Theory | 1. Cells can only come from cells 2.Every living thing comes from cells. 3.Cells are the base unit of life. |
| Explain why learning about the cell is so important in the study of biology. | 1. Cells are the base unit of our lives and to every living thing. 2. Cells create everything in our world and make it possible for us to live. |
