19 Cards in this Set

  • Front
  • Back
plasma membrane
'cell barrier ;transport,receptors,cell recognition
cytoplasm
'cell-forming substance' contains cytosol fluid,organelles & inclusions
mitochondria
'power plant'
ATP power synthesis
(more in muscle & liver cells)
ribosomes
'granules for protein
synthesis'
(some free & some attached to rough ER)
rough endoplasmic reticulum
'membrane factory'
where ribosomes attach for further protein synthesis;
(sends protein in transport vesicle to golgi apparatus-also stores Ca+)
smooth endoplasmic reticulum
'lipid & steroid synthesis'
smooth agranular,continuous w/rough ER,
golgi apparatus
'protein packaging'
sorts/modifies proteins carried from ER,delivers via vesicles to lysosomes,into cell membrane,to cell membranefor exocytosis
lysosomes
'intracellular digestion'
enzymes breakdown contents endocytosis vesicles including dmg'd cell parts
peroxisomes
'detoxifies potential toxins'
catabolizes free rad's from cell metabolism to hydogen peroxide(also catblze's poisons + fats in kidney +liver)
cytoskeleton
microtubules
microfilaments
'bones,muscles,ligaments of the cell'
cell skeleton
organelles move along microtubules
microfilaments allow endo/exocytosis
centrioles
'forms bases of cilia & flagella,forms spindles & asters'
play part in mitosis
(microtubules grow from centrosomes around core centrioles)
nucleus
'control center for cell & genes'
site of DNA
largest organelle
nucleolus
'ribosome subunit synthesis'
chromatin
'where transcription of genes in DNA to mRNA occurs'
colored part of nucleus
condensed/dark/coiled/DNA active during cell division
extended/light uncoiled DNA active during nondivision
Chromatin has chromosomes;chrmsms.,have DNA,DNA has nucleotides,nucleotides have genes,genes have bases(thymine+anenine&cystine+guanine
nuclear membrane
'transportation barrier between cytoplasm & nucleoplasm'
part of nucleus,outer layer=specialized continuation of rough ER
vesicles/vacuoles
'for cell membrane transportation of substances'
exocytosis-out of cell
endocytosis-into cell
phagocytosis-eating
pinocytosis-drinking
microvilli
maximizes surface area on wet epithelium (for absorption)
cilia/cilium
epithelial whips move mucus in one direction
flagellum
single long whip helps sperm swim
