This document provides information about eukaryotic cells, specifically liver cells. It includes a diagram labeling the structures of a liver cell, including the ribosomes, rough endoplasmic reticulum, lysosome, Golgi apparatus, mitochondrion, and nucleus. The functions of each structure are also annotated. Comparisons are made between prokaryotic and eukaryotic cells, as well as plant and animal cells. The roles of extracellular components in plant and animal cells are also outlined.
