light microscopy - ANSWERmagnification of cellular structures up to 1000 X
scanning electron microscopy (SEM) - ANSWERimage of 3D surface coated with heavy
metal like gold (100,000 X)
transmission electron microscopy (TEM) - ANSWERimage of ultra thin slice to view
intracellular components (500,000 x)
cell fractionation - ANSWERtechnique that breaks cells and separates their components
cytosol - ANSWERaqueous part of cytoplasm within which particles and organelles are
suspended
nucleoid - ANSWERdensly staining DNA region in a prokaryotic cell
chromatin - ANSWERuncondensed DNA wrapped around histones (used during
transcription)
chromosome - ANSWERcondensed chromatin (used during cell division)
nucleus - ANSWERorganelle that contains DNA and controls processes of cell
nucleolus - ANSWERorganelle where ribosomes are synthesized and partially
assembled (within nucleus)
nuclear envelope - ANSWERperforated double membrane that controls flow of
materials (around nucleus)
ribosomes - ANSWERorganelles made of protein and rRNA that direct protein synthesis
(in cytoplasm or tethered to rough ER)
nuclear lamina - ANSWERnetlike array of intermediate filaments that maintains shape
of nucleus
endoplasmic reticulum (ER) - ANSWERinternal membrane system in which components
of cell membrane and some proteins are constructed
rough ER - ANSWERorganelle continuoues with nuclear membrane, to which
ribosomes are tethered and proteins are synthesized for export
smooth ER - ANSWERorganelle where lipids are synthesized
