Phases of Mitosis (IPMAT)
interphase prophase metaphase anaphase telephase
interphase
cell performs reg. functions
copies its DNA
prophase
chromatin condenses into chromosomes
centrioles make spindle fibers
(can pick out defined lines in big nucleus)
metaphase
cell’s chromosomes align on middle of metaphase plate
anaphase
chromosomes break apart (pulled by spindle fibers anchored at opposite poles of the cell)
telophase
cell begins to cleave
2 daughter nuclei form
membrane forms around chromosomes
concentration gradient
difference in chem. concentration btw one point and another
filtration
mvmnt of H2O through a SPM due to hydrostatic pressure (force of gravity)
diffusion
net mvmnt particles from high concen. to low concen.
passive transport
mvmnt of particles across cell mem. w/out energy input
osmosis
net flow of water through SPM
from area high concen. to area low concen.
facilitated diffusion
carrier-mediated transport of solute through mem. and down concent. gradient
phagocytosis
“cell eater”
consumes cellular debris, dirt and bacteria
hypertonic
consumes water
concen. of NP solutes< intracellular fluid
hyptonic
repels water and shrivels (crenate)
concen. of NP solutes> intracellular fluid
isotonic
