Section 1

Question Answer
biology is the study oflife
all organisms possess DNA. DNA containsinformation for growth and development
instructions for traits that are passed from parents to offspring are known asgenes
homeostasis meanskeeping things the same
ecology is the study ofcommunities or organisms in relation to their environment
the smallest units that can carry on all functions of life are called cells
all organisms are composed ofcells
all living things maintain a balance within their cells and the environment through the process ofhomeostasis
complexity is not necessarily a characteristic of living things
living thingsneed energy for life, have the ability to reproduce & are composed of cells
cellular organization is a characteristic ofall living things
Dr. Ross suggested that the anopheles mosquito might spread malaria from person to person. this suggestion was ahypothesis
scientific hypotheses are most often tested by the process ofexperimenting
a hypothesis is a testable possible explanation of an observation
a unifying explanation for a broad range of observations is atheory
a hypothesis that does not explain an observation isrejected
scientists usually design experiments witha good idea of the expected experimental results
a scientific theory may berevised as new evidence is presented
the word theory used in a scientific sense meansa highly tested, generally accepted principle
scientists share their research results bypublishing in scientific journals & presenting at scientific meetings
Hookes discovery of cells was made observingdead plant cells
who was the 1838 german botanist that concluded that all plants are made of cellsMatthias Schleiden
when the volume of a cell increases, its surface areaincreases at a slower rate
a cell that can change its shape would be well suited formoving to different tissues through narrow openings
one difference between prokaryotes and eukaryotes is that prokaryotes have no nuclear membrane
a bacterium is an example of aprokaryote cell

Section 2

Question Answer
only eukaryotic cells havemembrane-bound organelles
one important organelle that helps maintain homeostasis by moving supplies from one part of the cell to the otherendoplasmic reticulum
numerous hair-like organelles that protrude from the surface of a cell and are packed in tight rows are calledcilia
the double membrane surrounding the nucleus is called the nuclear envelope
the place where plant cells have a large membrane-bound space which water, waste products, and nutrients are storedcentral vacuole
plant cells havechloroplasts and a cell wall
the correct order of organization of structures in living things, from simplest to most complex iscells, tissues, organs, organ systems, organism
this cell theory states the multicellular eukaryotes evolved from the single sealed prokaryotesendosymbiotic theory
grana, thykaloids, and storm are all components found inchloroplasts
the largest organelle in a eukaryotic cellcentral vacuole
chloroplasts are capable of convertinglight energy into chemical energy
the part of the golgi apparatus that is the receiving side is thecis face
the part of the golgi apparatus that is the shipping side is thetrans face
the inner part of the mitochondria that aids in chemical reactions is called thematrix
the name of the protein that allows for cell communicationglycoproteins
the cell wall in fungi is made ofpeptidoglycan
the cell wall in plants is made ofchitin
the cell wall in bacteria is made ofcellulose
the fluid protein of the cell is known as cytostol
these small molecules are able to pass through the phospholipid bilayer without the assistance of a protein channelO2, CO2 & H2O
the proteins that make up the cytoskeletonmicrofilaments
microfilaments are made ofactin and microtubules
who do you have to thank for your mitochondria mother
the function of the smooth endoplasmic reticulum in a liver cell is todestroy toxins
the scientist who contributed that cells can only come from pre-existing cells through cell division to the cell theory wasRudolf Virchow
