2.2 Subcellular Components of Eukaryotes
Cells—the basic structural and functional units of every organism—are of two distinct types: prokaryotic and eukaryotic. Organisms of the domains Bacteria and Archaea consist of prokaryotic cells. Organisms of the domain Eukarya—protists, fungi, animals, and plants—all consist of eukaryotic cells.
To Think About:
How do ribosomes reflect the common ancestry of all known life? What is the structure and function of the following subcellular organelles; ribosomes, rough ER, smooth ER, Golgi complex, mitochondria, lysosomes, a vacuole, and chloroplasts?
