(Questions and
Answers are

cells what are all organisms made up of
cell the simpliest collection of matter that can be alive
cells are near the middle where are cells compared to the biological size range
Scanning Electron focus electrons onto the surface of a specimen, providing
Microscope (SEM) images that look 3-D
transmission electron focus a beam of electrons through a specimen
microscopes
SEMs are 3D and what is the difference between scanning electron
TEMS are 2D you microscopes and transmission electron microscopes
look at SEMS
visually also
cell fractionation takes cells apart and seperates the major organelles from
one another.
centrifuges fractionate how does cell fractionation work
cells into their
component parts. they
take cells out through
centrifugation
to study nuclei what are cell fractionations used for primarily
plasma what are the basic features of all prokaryotes and eukaryotes
membrane
cytosol
chromosom
es
ribosomes
Cytosol semifluid substance
chromosomes carry genes and are protein coded DNA
ribosomes make proteins
in a region called the where is DNA in a prokaryotic cell
,nucleoid
no do prokaroytic cells have a nucleus
, nucleoid region a non-membrane-enclosed region of the cell where
prokaryotic DNA is found
they have no membrane do prokarotic cells have membrane
bound organelles. only the
outer membrane
The membrane at the boundary of every cell that
plasma membrane
acts as a selective barrier, thereby regulating the
cell's chemical composition.
DNA in a nucleus with what makes eukaryotic cells different from prokaryotic cells
a membrane
membrane bound
organelles internal
membranes
they are generally much
larger than prokaryotic cells
nucleus consist most of the cells genes DNA
nuclear envelope encloses the nucleus
nuclear pores regulate the entry and exit of molecules
lipid bilayer what type of membrane is the nuclear membrane
nuclear lamina what is the shape of the nucleus maintained by
protein what is the nuclear lamina composed of
chromatin DNA wrapped around protein
chromatin condenses to what happens to chromatin as the cell prepares to divide
chromosomes
each chromosome a single DNA molecule associated with proteins
nucleolus located within the nucleus and is the site of ribosomal RNA
synthesis
ribosomes particles made of ribosomal RNA and protein
ribosomes what carry out protein synthesis
Rough Endoplasmic bound to endoplasmic reticulum, has ribosomes
Reticulum
Smooth Endoplasmic no ribosomes, float around in the cytsol
Reticulum
Endoplasmic Reticulum more than half of the total membrane in the cell
Endoplasmic Reticulum what is the main part of the interior of eukaryote cells
the ER membrane continuous with the nuclear envelope
smoot what are the two distinct region of the ER
h ER
rough
ER
ER lumen folding with interior space
Synthesizes lipids what are the functions of the smooth ER
Metabolizes
