|
plasma membrane
|
membrane made of a double layer of lipids(phospholipids cholesterol),proteins are embedded,may extend thru bilayer or on only one face;externally facing proteins and some lipids have atached sugar groups
|
|
|
cytoplasm
|
cellular region between nuclear & plasma membranes,consists of fluid cytosol containing dissolved solutes,inclusions(stored nutrients,pigment granules,and organelles
|
|
|
mitochondria
|
rod-like,double membrane structures;inner membrane folded into projections called cristae
|
|

ribosomes
|
dense particles consisting of two subunits,each composed of ribosomal RNA and protein;free or attacheed to rough ER

|
|
rough endoplasmic reticulum
|
membrane system enclosing a cavity,the cisterna,and coiling thru the cytoplasm;externally studded w/ ribosomes
|
|
