|
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
|
