Electron Microscopy of the Cell mitochondrion lysosome peroxisome cytosol nuclear envelope Golgi apparatus nucleus vesicle endoplasmic reticulum plasma membrane The Nucleus nuclear envelope nucleus nucleolus • Most prominent organelle • Contains genetic information-DNA 2 m Cell membrane Rough endoplasmic reticulum ER Rough ER • Interconnected cisternae or tubules • Interconnected tubules • Ribosomes  protein synthesis • Steroid synthesis, .., .. Golgi apparatus • Organized into stacks of membrane-bound sacs from which vesicles bud off • Packaging of proteins • Post-translational modification of proteins (glycosylation, ..) • Sorting of synthesized protein to cell compartments Mitochondria Mitochondria 100 nm • Two membranes - inner membrane folded into cristae • Two compartments • Contain their own DNA • Reproduce •  ATP production (energy source)
