4b eukaryotes

golgi

lipid bilayer, trafficks protein, vesicles bud off

mitochondria

act & reproduce like bacteria (auto) → bacterial endosymbiont; respiration, double lipid bilayer, own DNA

nucleus

double lipid bilayer, most of genetic info, has nucleolus & nuclear pores

nucleolus

rRNA syntehsis

nuclear pores

traffic in/out nucleus

DNA

mult linear chromosomes, haploid/diploid, histones

histones

compacted protein that regulates DNA, archaea also has but not bact

ER

phospholipid bilayer

smooth ER

lipid metab, detox rxns

rough ER

ribosomes

80s

40s + 60s

ribosomes

translate tRNA to protein

cytoskeleton

intracellular protein matrix: actin, microtubules, intermediate filaments

actin

red, protein chains

microtubules

green tubulininter

intermediate filaments

regulate cell shape, motility

vacuoles

lipids sacs for storagecentra

central vacuole

turgor pressure

contracticle vacuole

reduce water

lysosome

digestive enzyme

flagellum

undulate, multiprotein complex
