a plant cell has
chloroplast
cell wall
central vacuole
animal cell has
centriole
animal and plant cells both have
mitochondria, nucleus, ribosomes, ER, vesicles, lysosome
chloplast is
found in plant cells
which kind of cell has more complex structures
eukaryotic
animals and plant cells are both
eukaryotic
the endoplasmic reticulum is the
cells organell, it can always be found close to the nucleus, ribosomes are attached to it
what has two membranes
mitochondria and chloroplast
mitochondria and chloroplast
reproduce by binary fission like prokaryotic cells
mitochondria and chloroplast
have their own ribosomes that look like prokaryotic ribosomes
mitochondria and chloroplast
have their own DNA
mitochondria and chloroplast have 2 membranes and
1) membrane from original cell
2) membrane from engulfing cells
eukaryotes have membrane bound
organelles, nucleus, and linear chromosomes
modern version of endosymbiotic hypothesis
for the origin of the eukaryotic organelles
refer to
book and go over the hypothesized steps
what is evidence for the Endobiotic system origin of the eukaryotic organelles
chloroplast reproduces by binary fission
according to the Endosymbiotic hypothesis, why did the large cells not destroy the small aerobic cells they engulfed
because they provide energy
which of the following is shared by both plant and animal cells
nuclei
what did chloroplast Evolve from according to the endobiotic hypothesis
photosynthetic bacteria
what is found in an animal cell but not in a plant cell
centrioles
what do eukaryotic cells have that prokaryotes do not
membrane-bound nucleus
how can plasmid be described
A small loop of DNA
what are the three tenets of cell theory
#NAME?
what instrument was essential to the development of the cell theory
light microscope
how long ago have prokaryotes believed to have evolved on earth
3.5 billon years
we have more ________ cells then _________ cells
bacteria cells
human cells
where is DNA found in an eukaryote cell
nucleus
where can DNA be found in the prokaryotic cell
nucleoid and plasmid
the prokaryot has DNA in
multiple locations
prokaryotes do not have
membrane-bound organisms
prokaryotes have different ways of
getting energy
-from heat
-from light (photosynthesis)
-from chemicals
-from breaking down (decomposing) other organisms
which existed longer
prokaryotes or eukaryotes
prokaryotes
prokaryotes are
-unicellular but may join in pair or colonies
-x10 smaller than eularote
-includes 2 groups of organisms bacteria and archaea
eukaryote are
-appeared about 1.5 billion years ago
-are separate branch on the tree of life called Eukarya
cell wall
surrounds the cell membrane
nucleoid
DNA is in a single loop chromosome
plasmid
small free floating loops of DNA coding for trait such as antibiotic resistance
Ribosomes
help translate DNA into proteins to carry out cell functions
flagellum
Used by the cell to move
all large organisms like humans have _______ living on and in them
-for us they
prokaryotes
make important vitamins
are essential helpers in digestion
Photosynthetic prokaryotes make up
much of the worlds phytoplankton
phytoplankton
-form the base of the aquatic food web
-Bring to the biosphere a large portion of the energy it depends on up to 90% of the earth atmospheric oxygen
tenet
part of a belief or doctoring believed to be true by all members of a group or profession
what did Virchow add to the cell theory
cells come from pre-existing cells
some cells are _________ and some are _________
unicellular
multicellular
______&________ put their ideas together to create the into all cell theory in 1838
Schleiden and Schwann
prokaryote
Single celled microorganism like bacteria that lacks a visible nuclei or membrane-bound organelles
what is a potential benefit for the research of the humane genome project
is that it will help find the genes responsible for many diseases
cell theory is
that cells are the building blocks of all living things
