describe nucleus
is admin largest organelle has double membrane chomosomes attaches ot nuclea lamina nucl envelope has pores has nucleolus inside
What is each organelle analagous to in the industrial cell analogy
admin - nucleus manufacturing - ribosomes, Rough and smooth ER processing - Golgi apparatus recycling, waster removal - lysosomes incinterator - peroxisomes powerplant - mitochondira/chloroplast security - cytoskeleton, cell wall
list organelles 7-8
nucleus ribosomes endoplasmic reticulum (rough and smooth) golgi apparatus lysosomes peroxisomes mitochondrion/chloroplasts cytoskeleton
describe ribosomes
manufacturing milliions makes proteisn made of RNA and protein
decribe rough endrplasmic reticulum
manufacturing associated with ribosomes memb is continuous with Nucl envelope and smooth ER makes many proteins folds and processing proteins before transportation
Describe smooth enodplasmic reticulum
manufacturing no ribosomes lipid processing center and storage facility makes phospholipids reservoir for Ca2+ ions
describe golgi apparatus
processing made of flat memb sacs has polarity cis pole is clost to rough ER and nucl trans pole is facing plasma memb packages proteins from ER and releases into vesicles
Describe lysosomes
recycling and waste removal degrade solic waste acidic breaks down and excretes things
what are 2 mechs for delivery of waste and by what
lysosomes phagocytosis - eat cell - cell memb surrounds and engulfs autophagy - organelle in cell dissolved by lysosome (+1 - receptor mediated endocytosis)
describe peroxisomes
incinerator where oxidation reactions occur grow indi of other organelles specific for each ox of molec
describe mitochondrion
power plant makes energy, atp has 2 memb 50 million grow indi to cell division
describe chlosoplasts
power plant makes eng in plants analagous to miochondria
describe cytoskeleton
netword of proteins and fibers give cell shape has role in motility and macromolec transfer
Describe cell wall
found in plants for structure, protection
