bio chap. 7 test

loading
what organelle converts the chemical energy in food tinto a form that cells can use?
mitochondrion
what contains genetic information?
chromosomes
organ system
organs that work together
organ
tissues working together
tissue
similar cells working together to perform function
levels of organization in a multicellular organism
individual cells
tissue
organ
organ system
cell specialization
different ways different tasks
exocytosis
merial fuses with cell membrane and forces contents out of cell
pinocytosis
pockets form on cell membrane, fill with liquid and pinch off to form vacuoles
pinecones need water to grow.
phagocytosis
exensions of cytoplasim surround a particle and make it into food vacuole

phago: sounds like ragu--sauce...food vacuole
endocytosis
taking material into cell using infoldings of the cell membrane

rforming a vacuole

ends the cells life and turns it into vacuole: ENDo
molecular transport
??/
active transport
requires energy
facilitated diffusion
when the cell membrane protien helps the diffusion of glucose accross the membrane
osmotic pressure
hypertonic side of selectivly permeable membrane

can cause cell to burst
makiing vulnerable to ijuries to cell wall
what can be isotonic?
two solutions
hypotonic
below strength

hippo- bellow the water
hypertonic
above strength

hyper: lots of energy
isotonic
same strength

iso: same
osmosis
diffusion in h20 through selectivly permeable membrane
equilibrium
when concentraion is alll the same
diffusion
when things move from high to low concentration
lipid bylayer
double layered sheet giving the membrane flexibility
concentration
mass/vlume
cell wall
protection and support
cell membrane
flexible barrierlayer
centrioles
2 in animal cell
organize cell division
cytoskeleton
network of protein filaments
help keep shape and move
lynn margulis
mitochondria and chloroplasts are prokaryote decendants.
prokaryotes evolved into mitochondria
chloroplasts
photosynthesis producing
what encloses the mitochondria?
outer membrane
inner membrane
mitochondria
organelles that convert chemical energy into food
vacuoles
containers
sac-like
hold things in single celled and some animal cells
lysosomes
clean up crew for cell
digests
enzyme filled
golgi appartus
modify
package
sort
materials from ER
smooth ER
no ribosomes
rough ER
ribosome endoplasmic reticulim
endoplasmic reticulium
produces lipids and other protiens
ribosomes
protiens are assembled on
small particles of RNA
nucleolus
ribosome assembly
chromosomes
chrommatin condensed genetic information passing things
chromatin
dna bound to protien
what covers the nuclear envelope?
nuclear pores
nuclear envelope
2 membranes
allow things to move in and otu of nucleus
the nucleus contains nearly all the cells ______. with it the coded instructions for making protiens and other important ______.
dna
molecules
TEMS
transmission electron microscopes
thin samples
SEMS
scanning electron microscopes
electrons scanned over regular specimin to produce 3-d image
only for nonliving preserved things
cytoplasm
cell otuside nucleus
organelles
specialized organs
prokaryotes
don't have nucleui
genetic material is not in nucleus
eukaryotes
have nucleui
nucleus in which genetic material is separated.
nucleus
cell brain. holds cell genetic material DNA
scanning probe microscopes
looking at DNA
cell theory
cells compose all living things
cells are the basic unit of structure
and function
cells come from cells
rudolf virchow
cells come from cells
theodor schwann
animals are made of cells
mattais scleiden
all plants are made of cells
anton van leeuwenhoek
single lens micrscope to observe pond water; everything has cells
robert hooke
compound microscope
cells- monasteries
