Who is the scientist who developed his own microscope and discovered living organisms in the things he observed?
100
1000X
What is the maximum magnification a compound light microscope can reach without blurring the specimen.
100
the basic structural and functional unit of all living organisms.
What is a cell?
100
the "powerhouse" (energy producer) of the cell.
What is "mitochondria"?
100
the diffusion of water
What is osmosis?
200
a) all living things are composed of one or more cells
b) cells are the basic unit of structure and organization of all living organisms
c) cells arise from pre-existing cells and pass on their genetic material to their daughter cells
What is cell theory (or the three principles of the cell theory)
200
the specimen must be dead, must be sliced very thin, and must be stained with heavy metals.
What are the three qualifications for specimen observation using a TEM?
200
all cells have this in common!
What is plasma membrane?
200
where genetic material in the cell is located
What is "inside the nucleus"?
200
substances are secreted at the plasma membrane.
What is exocytosis?
300
Robert Hooke
Who is the 17th century scientist who is credited for creating the term "cell".
300
3-D
What is the type of image quality projected when using an SEM?
300
it contains a nucleus and other organelles that are bound by membranes; a skin cell is an example
What is eukaryotic cell?
300
the "clean-up crew" of the cell. Contains enzymes that digest excess cellular material.
What is "lysosome"?
300
temperature, pressure, and concentration
What is "the three factors that affect the rate of diffusion"?
400
Is Latin for "small rooms"
What is cellulae
400
only non-living cells and tissues can be observed.
What is a disadvantage of using the SEM and TEM?
400
specialized structures that carry out specific cell functions--located within the cell cytoplasm
What is "organelle"?
400
the phospholipid "sea" in which embedded substances float...
What is "fluid mosaic model"?
400
uses channel proteins and carrier proteins to move substances across the plasma membrane.
What is "facilitated diffusion"?
500
Virchow, Schleiden, and Schwann
Who are the three scientists whose discoveries and observations largely contributed to the development of the cell theory.
500
consists of a series of glass lenses and uses visible light to produce a magnified image
What is a compound light microscope?
500
have a cell wall, chloroplasts, and a fixed shape
What is "plant cell"?
500
the process of maintaining balance inside a cell is...
What is "homeostasis"?
500
the concentration of water and solutes is equal in the cell; there is no net movement of water; cells retain their normal shape
