-plasma (cell) membrane -cytoplasm -nucleus |
|
nuclear envelope |
the double-layered boundary of the nucleus |
|
nucleus contains |
DNA and chromatin |
|
chromatin |
structural and regulatory proteins forms chromosomes during cell division |
|
nucleolus |
a nonmembranous structure composed of RNA and protein; site of ribosomal formation |
|
Endoplasmic reticulum |
numerous canals that serve in transporting molecules as proteins thru out cytoplasm |
|
ribosomes |
synthesize proteins and are located free in the cytoplasm or on the surface of the rough ER |
|
if ER lacks ribosomes on the surface, it is called |
smooth ER and doesn't serve as a region of protein synthesis |
|
Golgi apparatus |
composed of flattened membranous sacs, the site for packages glycoproteins for transport and secretion |
|
mitochondria |
"Powerhouse" of a cell. possess double membrane and provide the main location for cellular energy production of ATP |
|
lysosomes |
membranous sacs that contain intracellular digestive enzymes for destroying debris and worn-out organelles |
|
vesicles |
membranous sacs produced by the cell that contain substances for storage or transport, or form from pinching off pieces of the plasma membrane |
|
cytoskeleton |
contains microtubules, intermediate filaments, and microfliaments that support cellular structures w/in the cytoplasm and are involved in cellular movements |
