what are all living things made of?
|
Cells
|
|
|
what is the smallest unit that can preform the basic activities of life?
|
the cells
|
|
|
The studies of whom proved that cells divide, hence the evidence that life comes from life?
|
Robert Hooke, and Antone Van Leeuwenhoek
|
|
|
what theory is based on the observation and data collected in these studies?
|
the cell theory
|
|
|
cells have a great diversity of what?
|
shapes and sizes
|
|
|
cells are what?
|
unicellular
|
|
|
the single cell of an unicellular organism does what?
|
all that is necessary for the organism to survive
|
|
|
organisms made up of many cells are called?
|
multi-cellular
|
|
|
a multi-cellular organism is a?
|
community of specialized cells. Different types of cells in an organism preform different functions
|
|
|
cells are separated into different categories based on what?
|
the location of the genetic material
|

|
the location of the genetic material
|
|
|
what are the two different categories that classify cells?
|
prokaryotic and eukaryotic
|
|
|
prokaryotic cells are?
|
cells that have no organelles and the genetic material is the cytoplasm
|
|
|
eukaryotic cells are?
|
cells that have membrane-enclosed organelles and the genetic material is a structure called the nucleus
|
|
|
what do cells do?
|
they carry out the functions needed to support life
|
|
|
what is the hierarchy of multi-cellular cellular organization?
|
cell, tissue, organ, organism
|
|
|
what led to the discovery of cells?
|
microscope
|
|
|
what are cells measured in?
|
micrometers- um, a micrometer is one millionth of a meters
|
|
|
what do microscopes do?
|
they magnify objects and make them appear larger, up to 1000x larger
|
|
|
what did Robert Hooke observe?
|
tree bark, dead cells
|
|
|
what did Antone Van Leeuwenhoek observe?
|
moving (living things) in pond water
|
|
|
how do light microscopes work?
|
the lenses are used to bend light; sometimes cell samples treated with dye to make structures in the cells easier to see
|
|
|
what is the advantage of the light microscope?
|
can observe living cells, used for objects larger than .2 ums
|
|
|
how does the scanning electron microscope work?
|
electrons are used to produce images. The object is coated with a heavy metal, then a beam of electrons run back and forth over the surface; a 3-D image is produced
|
|
|
how does the transmission electron microscope work?
|
electrons pass through a thinly sliced section of a cell producing a 2-D image
|
|
|
what is a disadvantage for the TEM and the SEM?
|
the cannot be used for studying live specimens
