involved with cell division and chromosome movement
centriole
plastids which produce organic food
chloroplast
membrane bound sac of digestive enzymes
lysosome
site of stored genetic information
nucleus
membrane bound vesiciles which hold enzymes to oxidize
peroxisomes
network of filaments and tubules for cell shape
cytoskeleton
9 microtubule doublets used for movement
cilia/flagella
uncoiled chromosomes
chromatin
used for ATP production
mitochondrion
processing and packaging of molecules from the ER
Golgi apparatus
motor molecules which work with myosin
actin filaments
in plants, a large fluid filled membraneous sac
vacuole
globular proteins arranged in hollow tubes used for movement
microtubules
tiny membraneous sacs which hold and transport molecules
vesicle
site of protein assembly
ribosome
membraneous channels where proteins are synthesized (continuation of the nuclear membrane)
endoplasmic reticulum
phospholipid bilayer with embedded proteins which controls and regulates materials which enter and leave the cell
plasma membrane
process by which amoeboidtpye cells engulf large substances, forming an intracellular vacuole
phagocytosis
type of transport which uses ATP to go against the gradient
active transport
selectively interacts with the molecule or ion so it can specifically pass the plasma membrane
carrier protein
glycoprotein that helps the body defend itself against pathogens
cell recognition protein
proteins with sugars attached
glycoprotein
phospholipids with sugar attached
glycolipids
allos a particular molecule or ion to cross the plasma membrane freely
channel protein
what gets dissolved
solute
what the solute gets dissolved into
solvent
movement of molecules from an area of high concentration to an area of low concentration
diffusion
% of solute = % of solvent
isotonic
% of solute > % of solvent
hypertonic
% of solute < % of solvent
hypotonic
the pressure of the cell contents against the cell wall when the central vacuole is filled up
turgor pressure
what happens when a cell is placed in a hypertonic solution?
water leaves the cell
what happens when a cell is placed in a hypotonic solution
water enters the cell
what happens when a cell is placed in a isotonic solution
nothing
result of a cell being placed in a hypotonic solution
lysing
contraction of red blood cells within animals in a hypertonic solution, due to the loss of water through osmosis
crenation
3 sodium in, 2 potassium out
sodium-potassium pump
when NaCl cannot leave the cells
Cystic fibrosis
